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.

The new Log View provides an in canvas experience for model errors and warnings allowing you to maintain the application focus during building.

XPTIN files respect the boundary conditions of imported data, including Imported LandXML Files. 


Large LandXML Surfaces above 2 million points are now supported with the 64-bit application. 

LandXML Surface format support includes importing point, breakline and or contour data in creating an XPTIN. 

User Interface Changes 

New: Transmit Model Feature available from File > Transmit Model. 


File Open works with Transmit Model zip archives zip files 

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.

New Atlas 14 Temporal Distribution XPX Generator tool is now available. 

Updated Ruler tool now includes a deflection angle.
