This topic lists the additions and improvements incorporated in InfoWorks® WS Pro Version 2025.5 which were not available in previous versions.
Please note that this new version also includes various bug fixes that are described in detail in the Release Notes.
See Known Issues for a list of limitations that we are aware of.
Improved performance for Lagrangian WQ calculations
The Water Quality solver using the Lagrangian method has been updated to achieve faster performance, resulting in a 25% reduction in run times when using that option.
Apply WQ Solute parameters on pipes based on material for MSQ engine
WQ Pipe Constant values can be assigned in bulk based on material through the Model drop-down menu. This enables easier variation of water quality parameters based on pipe materials. The parameters can also be assigned through Ruby scripting.
MSQ support for additional solute unit types
You can now control the display unit type for MSQ solutes. In addition to concentrations, solutes can be displayed as time duration as well as percent. The units and solute description will appear in charts and grid views for display.
