The following list provides the new and exciting features in XPSWMM/XPStorm.

New and Noteworthy Features in 2019.1.3

Maintenance

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.

New and Noteworthy Features in 2019.1.2

XP2D Extreme

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.  

New and Noteworthy Features 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. 


New and Noteworthy Features 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. 

User Interface Changes 

New: 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 Encrypted Models in XPVIEWER. 


User Productivity 

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.
