PyroSim 2023.3

What's New

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.

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
