PyroSim 2023.3.1206

Faster FDS modeling with professional results

Version: 2023.3.1206

December 6, 2023

What's New

PyroSim 2023.3 introduces new features for review and verification of your models.

This version of PyroSim is designed for FDS version 6.8.0 and uses version 20.0.2+9 of the OpenJDK Java VM.

Model Checks

Using an approach similar to our libraries for materials, surfaces, and other items, you can create, save, and share a library of model checks across PyroSim files.

Example of an FDS Model Record Check filter.

With the launch of this feature, we have included four initial check types - A general FDS record test, calculation of total heat release rate for a surface, and calculation of total surface supply or exhaust.

All Changes since PyroSim 2023.2.0816:

Model Checks
  • Added a Model Checks feature that verifies user-defined values in models prior to beginning simulations. Documentation
Performance Improvements
  • Improved the rendering performance of the Record View when rendering large files
Other Updates
  • View tools will now reset to defaults when user uses the "New" command.
  • Added a "New FED Device" action to the Devices menu.
  • Added the ability to define an assumed Activity Level on FED Devices.
  • Updated import libraries for IFC and DWG files.
Bug Fixes
  • Fixed a crash that occurred when creating a new HVAC Node or Duct Device.
  • Fixed a crash that occurred getting the last committed mouse point.
  • Fixed bug that could cause the Check for Updates dialog to direct localized build users to a non-localized update path.
  • Fixed a UI Bug that would leave a visual artifact on tool buttons after canceling sticky mode while using the Light Theme.
  • Fixed a UI bug that could cause buttons to change size when a dialog was moved to a different screen.
  • Fixed a UI bug that could cause invalid editor fields to change size.
  • Fixed some UI bugs in the Manage Floors dialog.
