Features and Improvements in 2020.1
XP2D Extreme – Quadtree for Multiple Domains
The Quadtree for Multiple Domains feature enables variable-sized grids that allow the modeler to focus on detail where needed. This provides flexibility to reduce simulation memory and decrease computational speed. As seen in the following example of a pressurized bridge, the use of the Quadtree mesh to the model produces sharp details for a greater focus area while reducing memory load.
In the image below, various Quadtree levels allow the modeler to focus calculation resources on areas of most interest. In this case, the urban streets, overland flood route into the planned neighborhood, and between the homes, while reducing the base Quadtree extents to an acceptable resolution where no flooding is known to exist. For more information, refer to XPSWMM and XPStorm 2020.1 Quadtree and Sub-Grid Sampling FAQ.
Quadtree for Multiple Domains is available when XP2D Extreme is enabled in 2D Job Control Settings. The Multiple Domain module is accessible to existing users on Complete and Premium bundles.
With this release, the recommended Viscosity Formulation is recommended to be Wu. This recommendation is less sensitive to cell size and provides a better fit. See Viscosity Formulation recommendations.
Sub-Grid Sampling for XP2D Extreme
Sub-Grid Sampling (SGS) enables the sub-2D cell terrain data of the DEMs, TINs, and Z shapes to be used to construct the model, rather than represent each 2D face and 2D cell as having one elevation. This methodology prevents trapped water and accounts for cells partially in channels, which results in sharper 2D maps and more accurate flood extents.
SGS is available when XP2D Extreme is enabled in 2D Job Control Settings. It is accessible to all users with existing 2D functionality.
Pressurized Bridges in the 2D Domain
With this release of XPSWMM/XPStorm, the XP2D Extreme Engine will support Layered Flow Constrictions accelerated by both the GPU module and working with Quadtree domains.
- XPSWMM compiles with Visual Studio 2019 and Intel Fortran 2019.
- Floating Deck and Bridge Flow Constrictions not supported in XP2D Extreme Engine. We suggest migrating those non-layered flow constrictions to layered flow constrictions.
- XP2D and XP2D Extreme now use the Tuflow 2020-10-AA engine.
- ARR Storm Generator updated to latest .NET Version for the use of the OSM Maps.
- XPSWMM now requires .NET Framework 4.8 or later.
- When Subgrid Sampling is on, and Use DTM is selected as the Surface, XPSWMM will export the XPTIN to LandXML. Depending on the size of the XPTIN, expect a performance delay in writing and sampling large LandXML TIN surfaces. For best performance, use a binary float (FLT) terrain.
- A single-layer Quadtree model can be created using a single Level 1 extent only for users who do not have multiple domain module licenses. Please note that single-layer Quadtree will process slower than the regular grid.
- The Cell Side Wet/Dry Depth command removed as this is no longer valid.
- Innovyze Product Feedback URL added to the Help menu.
- XP2D Utility Interface is now a 64-bit application allowing larger results files associated with the XP2D Extreme engine results to be processed.
Features and Improvements in 2019.1.3
Bridge link hydraulic efficiency table issue has been addressed. An issue where certain bridge links that contain simplified cross-section resulted in a linear interpolation of the wetted perimeter between the low chord and lowest cross-section Y values. As a result, the engine now evaluates a minimum set of records to correctly represent the bridge that better fits the hydraulic efficiency of the bridge section over a range of depths.
The Cross-Section Properties dialog box now works as expected
Table E15 now correctly lists Junction Names when Junctions exceed the number of links.
Gauged Inflow File no longer encounters no file format specified errors.
Features and Improvements in 2019.1.2
The application no longer halts the simulation when an SX 1D/2D connection line is used with an open-channel link. This situation is now supported correctly and errors will only be encountered with XP2D Classic.
Ridgelines and Gully lines now correctly alter 2D Domains in XP2D Extreme Analysis.
Features and Improvements in 2019.1.1
XPSWMM 2D now uses the latest 2018-03-AE engine build
The Tuflow 2018-03-AE engine build is now included in XPSWMM 2019.1.1, which fixes a number of issues experienced in the earlier versions.
Percent Impervious field is now moved to Landuse Properties
Percent Impervious (%) field in the 2D Landuse dialog is moved from inside the Infiltration portion of the dialog to the 2D Landuses Properties portion. This value is written in the LandUse.
New warning message in the LA Hydrology method
The application will now give a warning message when the Time of Concentration is less than five minutes when using the LA Hydrology method.
Features and Improvements in 2019.1
XPSWMM and XPSTORM is now a 64-bit application matching the 64-bit xpswmm simulation engine.
This release focuses on a general theme of stability and performance to enhance the usability of the application to complement the release of XP2DExtreme in the prior release.
The application file open and read times have been reduced. The application has considerably more memory available for modeling information.
This changes the supported database driver connections used in the GIS Link databases. The 32-bit and 64-bit versions conflict with each other requiring an update to the Microsoft Access Database Engine or replacement of the 32-bit Office 2007 Database engine used to connect to GIS Databases or Excel Workbooks. Please check the Third-Party installation Guide page for more information.
During the opening of an existing model, a command prompt window will open and process the old scenario manager database into the SQLite database format.
In doing this, the installation directory is now C:\Program Files\Innovyze\xpswmm 2019.1_x64. The application folder structure changed to facilitate easier access to the tools you typically need to find.
The new Log View provides an in canvas experience for model errors and warnings allowing you to maintain the application focus during building
- The Log View allows filtering of errors, warnings while preserving the application focus. Each error and warning is linked to a 1D element allowing you to rapidly locate and zoom to the element in question preserving time during the model development process.
XPTIN files respect the boundary conditions of imported data, including Imported LandXML Files
The import of surface information will properly import the boundary conditions included in the file, including LandXML and XYZS data imports into XPSWMM and XPStorm.
The boundary not retroactive to existing XPTIN files, but any new XPTIN files created in 2019 will import with the proper boundaries.
The use of the DTM > Surfaces Hierarchy allows you to layer XPTIN's for use with XP2D and XP2D Extreme.
Large LandXML Surfaces above 2 million points are now supported with the 64-bit application
Large XPTIN files can increase file open load times. XPSWMM now checks XPTIN file sizes at the 500 MB default setting and allows you to skip loading the XPTIN file. If the XPTIN is less than the warning setting, no warning occurs and the XPTIN automatically loads. If the threshold is set too low, a new threshold can be set in the INI file accordingly.
LandXML Surface format support includes importing point, breakline and or contour data in creating an XPTIN
Bentley LandXML surface exports typically do not include the triangle export as a default setting, but includes contours, points and other breaklines. XPSWMM/XPStorm now support the XPTIN creation process where only raw data is included in the surface section of a LandXML file.
Transmit Model Feature available from File > Transmit Model
Opening a Transmit Model zip file is now supported by the application and the viewer application. The file will unzip all results, model element, GIS, CAD images and the surface data in subfolders within the archive location and keep all paths as working.
Encrypted Models can be used the Transmit Model to send an archived zip file to XPVIEWER users.
File > Open works with Transmit Model zip archives zip files
Opening an Archive Model works with the Transmit Model feature.
Opening an Archive Model works with Encrypted Models in XPVIEWER.
Bridge Pier Editor values now supported in XPTables for edits.
X1D Check files setting in the 2D Job Control making it easier to debug 1D-2D Connections.
2D Grid Polygon Dialog box now includes an Apply button that allows the recalculation of 2D Grid cells count and redraws the grids in canvas without leaving the dialog box.
Most Recently Used Model list default to the latest ten files.
Snap to Grid functionality extended to work for all 1D, 2D, Topographic and Time Series output values.
Map Output to GIS ASC Format option is now available in the 2D Job Control.
2D Job Control now accessible from an icon button on the toolbar.
2D Land User Reference workflow enhancements for better productivity.
The workflow now shows the 2D Global Data Material ID in the 2D Land Use dialog box.
2D Land User Reference now allows the position of the Material ID to work according to the Tuflow guidelines for the position of the attribute in the DBF file. The workflow now includes the 2D Global Data Material ID is now shown in the 2D Land Use dialog box.
Relative Paths now work in the Advanced 2D Settings.
New Atlas 14 Temporal Distribution XPX Generator tool is now available.
Quickly download the Atlas 14 Distribution Temporals from the NOAA Website and build XPX files quickly.
Updated Ruler tool now includes a deflection angle.
To add in a review of models and entrance and exit loss coefficients, the Rule Tool will now report the angle formed from the last three selected points.

- The Horizontal and Vertical Elliptical Pipe dialog box correctly responds to reflect the correct rise/width values. These pipes now export correctly for newer releases of EPASWMM5.
- Exporting the DTM to GRID did not always export the surface to the correct location. This has been fixed and now exporting to GRID creates a surface in the expected location
- An issue where an incomplete model was exported has been resolved by requiring a save prior to the model export to EPASWMM5, LandXML or XPX Export.
Features and Improvements in 2018.1
- In Runoff mode, a new tool to provide the ability to split a catchment into the impervious and pervious sub‐catchments is now available. The Tools > Calculate Node > Split Catchment in Perv/Imper tool has now been provided. The tool provides you of SCS or Laurenson hydrology methods the ability to perform better simulations and provides the ability to make sub‐catchment redirections from the impervious to pervious sub‐catchment.
- A new FIELD STATISTICS tool in XPTABLES allows you to select a column or part of a column and generate the Maximum, Minimum, Mean, Sum and Standard Deviation of the contents selected.
- A new Block Edit tool in XPTABLES allows you to perform group edit functions on a selection of cells:
- Equal to: replaces all selected cells with the new number or string.
- Add: Adds the entered value to each selected cell.
- Subtract: Subtracts the entered value to each selected cells.
- Multiply By: Multiply the entered value to each selected cell.
- Divide By: Divide each selected cell by the entered value.
- Ascending and Descending icons now available in XPTABLES.
- The Review Results for a Hydraulic Node now has a new graph button (Inlet Capacity) that provides the direct time series results for Inlets display. The new icon (IC) in the Review Results allows you to display flow and levels for selected nodes with Inlet Capacity enabled.
- Tooltips are available in the Media Control bar for 2D and 1D flood animation.
- The Dynamic Long Section (Profile) and the Dynamic Section Views shows an interpolated line of node ground elevations when no DTM exists in the model.
- The NRCS and NOAA Temporal Distributions are now available at the Resource Downloads area.
Features and Improvements in 2017.2
- The software will now offer an option to solve the model with the Solve Manager when the total number of storms or scenarios exceeds 50 model runs.
- The Solve Manager has been successfully tested using 2000 Global Storms.
- When a model is solved by using the Solve Manager, the engine windows and Solve Manager windows now start minimized. This ensures that there is no interruption to other programs and allows the solve to be in the background.
- The Engine dropdown is now disabled in the Solve Manager UI to prevent the user from selecting incorrect engine type.
- A warning is generated when more than 2000 storms is attempted to be solved with Solve Manager.
- An issue with result windows open was previously not handled correctly with the Solve Manager option. This is now correctly managed and results windows can be closed by the application and the solve will proceed correctly.
- To make the Box and Whisker plot practical for use, an option to filter the AEPs the Box and Whisker plot by a combo box. Now the results can be filtered to view an individual AEP allowing easy identification of the critical duration/ensemble for that AEP.
- While using the ARR Storm Generator if the ARR Data Hub Text File does not contain any temporal patterns, then you can select an Increments File to be loaded. These will be used to load temporal patterns that are included in the generated Rainfall Global Databases
- The user is allowed, in conjunction with ARR 2016, to enter the number of pre-burst timesteps (let's call this N) that would represent the anticedent / pre-burst rainfall. Then when the storms are imported and generated the median pre-burst rainfall depths from the ARR datahub text file, the program places N increments of value 'pre-burst ratio for that AEP and Duration divided by N' before the main temporal pattern.
- The ARR Data files (Data Hub Text file, Temporal patterns file, and IFD table file) can be downloaded including selection from map. Conversion to XPX and import to XP is now all available from the Select ARR Data Files dialog.
- The number of Global Storms has been increased to 2000. This now allows ensemble groups such as sets of storm shapes to be simulated for multiple durations and multiple return periods. Clearly this could have hit the previous limit of 100.
- As part of the overall new feature for updated ARR procedures, a new tool has been created to fetch ARR 2016 data files directly from respective websites/APIs.
- When doing a Save As for an existing model, the .XP extension is forced as it is for a new model.
- Gutter, Width, Velocity, and Depth are now available for display in XPTABLES. Previously, these values were only showing in the model output file in Table E9.
- A new tool to clear 1D Results in the Results menu will remove the model contents in the 1D folder for all scenarios and Global Storms. This will also clear the contents of the .JSON file, which holds some specific Hydrologic and Hydraulics results for the new Global Storms Ensembles.
- Invert Elevation label has been added to the HDR: Node Data dialog.
- In version 2016 through 2017.1.1, nodes with inlet capacity did not report the surface node storage for maximum surface area but rather reported the subsurface node area. This has been put back to the earlier intended way. In all versions the model, output file reported all the surface areas of surface and subsurface nodes.
- The software now protects itself from attempting to triangulate a set of 0,0,0 or identical points for the DTM. In older models, these situations may have resulted in an adverse situation but now the message "Cannot Create TIN file, no triangles generated" is displayed.
- A persistence issue in the Variable Time Interval rainfall dialog has been fixed. For example, the selection of Absolute depth can now be remembered.
- Inappropriate menu items were removed from the File menu when inside result windows such as Review Results or xptables.
- In the case of missing results for active scenarios and global storms not solve: for example, many error messages have been displayed for each missing time series. These messages are now directed to a new ReviewResultsErrors.txt file.
- Individual or Ensemble groups of storms can now be selected in the Review Results for time series graphing.
- Some overlapping text has been detected with catchment labels. This has now been fixed and cosmetically, it appears much cleaner and will draw faster with one single write of text to the screen.
- Statistics for the processing of many Global Storms is now included. Columns have been added to identify the storm that generates the result closest to the average of many storms.
- In the xptables view, the menu has been trimmed to only show appropriate items in the Window menu.
- Deleting Time Series Output lines and points could cause adverse issues when no extent was defined in the project. This has now been resolved and these objects can be deleted either graphically or from the Layer Control Panel without affecting program stability.
- New XPX commands exist for the Rainfall data and time fields: - R_RAINSYR, R_RAINSMTH, R_RAINSDAY, R_RAINSHR, R_RAINSMIN, R_RAINSSEC. These allow separate imports whereas the previous imports of F_R_TZRDT and F_R_TZRTM brought in all date and time fields respectively.
- A new Global Storm XPX command has been created. This allows import of storm name, ensemble name, and all other parameters for the row. For example, GLOBAL_STORM 0 1 ""CS_63pct_10min1"" ""CS_63pct_10min"" ""ARR 63.2%"" ""CS_63pct_10min1"" 1 1, it is also documented in the online help.
- Hydrology and Hydraulic model results when using Global Storms and Scenarios are now stored in a JSON file. This partly ensures fast response and reasonable .XP file sizes for those types of models.
- Models that are saved in more recent versions can no longer be opened in older versions beginning in 2017.1. This has been implemented to ensure database compatibility and the integrity of the data.
- Since the Global Storms is upgraded to include Ensemble groups when opening older models, the existing storms are now merged to an Ungrouped Ensemble to fit the new structure.
- Infiltration values (Storm Losses) can now be imported from the ARR Data Hub text file. The import creates a Global Database record from the text file.
- Double Precision engine selection is no longer forced for GPU solving of rain on grid models. This is desired for optimum run time and it is already part of the GPU solver. It is still recommended for CPU solutions.
- After a Merge command, an automatic Save is no longer invoked. This means that the user must now decide to save the merged model. This new choice now allows a merged model to be discarded and does not force the acceptance of the merged model.
- As part of the ARR enhancements and for the speed of processing many global storms, the subcatchment results are now stored and retrieved from a JSON file. This file will be located in the same folder as the .XP file and will be necessary to pass to another user wishing to retrieve catchment results without rerunning the model.
- A full set of Object Names and Object ID are now written in the model output file. This allows easier recognition of tables in the output file when an object ID is used in place of long object names (>20 characters).
- An issue with the combination of Global Storms or Scenarios and 1D flood maps has been resolved. In some cases, the individual storm results were not appearing but the Base Scenario result would appear in its place.
- The user can now toggle on and off in Dynamic Long Section and Dynamic Section Views the X,Y display with the cursor. The default is ON. It is also persistent in the model.
- The export of catchments now includes Catchment Name, Target Node, and Catchment Position (1-5) as the attributes in the exported GIS files.
- The evaluation version of the software is now limited to 100 subcatchments. This is justified since there is a limit of five per node and 20 nodes. The limit was previously 50.
- A message stating "Encountered an improper argument" has been removed when turning on 1D Flood maps when no 1D Flood Maps exist. Now, the dialog will launch showing a null range for the result.
- Some cosmetic issues were addressed in the infiltration dialogs regarding the text alignment with the embedded images.
- An abnormal termination was occurring when the model was attempted to be solved while result windows were open. Although a message occurred to close the Windows, they were not closed. This is now fixed for the 2017.2 version.
- The menu items of New, Open, and Save As while in the Review Results window have been disabled as they are not pertinent in that view.
- There were occasions where while leaving some result windows open, a crash could occur if the main program was closed before closing other windows. This has been fixed and no crash occurs when closing the program regardless of the choice when prompted to save the model after selecting a closing option.
- The dialog Copy icon is now disabled as opposed to generating a database error message. This type of data cannot be copied from object to objects and hence the disabling of the icon is appropriate.
- Clicking Run in the Utilities without entering underlying data for the utility will now correctly display the error and warning messages for all language versions.
- Version 2017.2 and later allows the user to switch between supported languages. The translated strings are included as XML files for Japanese, Korean and Chinese. Other languages are anticipated for version 2018.1.
- Various dialog cosmetic issues have been addressed for the Chinese version including the UK hydrology methods dialogs.
- The text alignment in the subcatchments dialog has been improved for the Korean version.
- An issue with very large models and non-English regional settings has been resolved. This issue was apparent only when the INI setting OPT_OBJ_NAME_ACCESS=ON was present.
Features and Improvements in 2017.1
- The configuration parameters PUMP3_MAXQ or MAXQ_PUMP3 are now on by default. They allow the pump to choose the flow with the lowest head on the pump if the pump is found to be off the pump curve such as flowing downhill. Previous versions could not pump downhill without the parameter since no negative head values are on the pump curve and hence no corresponding flows for those pump situations.
- Within the Grid Extent Properties dialog, you can now set the precision of the Cell Center Elevation from 0 to 10. Typically this will be 2 for US Customary projects and 3 for metric models. This is now extended to the 2D Map results. For example, when showing the Max Depth Result for every cell, the number can be set to show 2 decimal places to represent one hundredth of a foot or every cm for a metric model.
- XPSWMM can now be configured for only 1D Sanitary Sewer modeling by selecting that menu item in the Configuration menu. This disables certain functions and layers in the layer control panel that do not pertain to that type of model such as 2D modeling.
- Adaptive time stepping is possible for GPU model runs. It is accessible in the 2D Job Control 2D Only Mode section.
- When resolving a model if there are opened result windows the user is now prompted to close all Tabs with one click.
- When assigning catchments to node, those nodes that are on the perimeter or very close can be included in the selection of node as a possible target.
- When a new Global Database record is added, it is automatically selected so that clicking the Edit button will allow the new record to be edited without clicking the item in the list.
- The configuration parameter for allowing maximum flow through a pump, when the head is zero or negative, has been placed in the online help.
- Review Results time series, such as Runoff hydrographs at nodes and stage graphs in Hydraulics, now include in all cases a first time step at time equals zero and a final time step in the displayed and graphed series.
- The full build number is now being presented in the License Details.
- The library for loading and reading CAD files has been updated to allow the latest versions of CAD files.
- The installer has been upgraded and will no longer allow the XCF file to be moved on to itself by selecting the file from the same place as the target during installation, which caused issues in the past.
- A new feature has been added to the Tools > Modify Elevations to match the crowns or match the inverts of a set of selected links and nodes.
- xpdiagnostic.exe has been updated for the current version.
- Maximum water surface elevations for bridge links are automatically set to 10 m or 30 ft, depending on units above the high cord value. This ensures that the weirs used for the overtopping remain weirs and do not become orifices or the SWMM default at the weir surcharge elevation.
- The current XPSWMM/XPStorm installers no longer have a direct download for XPDRAINAGE but rather some links to learn more and request an evaluation copy.
- GPU solves do not force Double Precision engines when there is a rain on Grid simulation.
- The old CHM files are no longer part of the XPSWMM/XPStorm installers. The program help is all online except for the Japanese version at help.innovyze.com.
- In an effort to streamline multiple language version of XP, we now use a single xps_res project for all resources dlls.
