Build Stadiums and Theaters with Inferred Stairs

December 9, 2021
Sometimes Pathfinder models include stair access for occupants which are modeled without any of the user-defined stairs tools. In Pathfinder 2021.4 this modeling technique is automatically detected and occupants traversing the stairs now move according to stair behavior appropriate for the determined riser and tread distances. With the inferred stairs feature, Pathfinder users now have more flexibility in creating complex stairs without sacrificing in movement accuracy. Read More...

Automatically Partition Meshes to Optimize Simulation Time

November 23, 2021
PyroSim has previously offered many ways to help users create the most efficient meshes for their models by providing cell calculations, a refinement tool, and a splitting tool. In PyroSim 2014.4 we will introduce mesh partitioning, which automatically divides one or more meshes into equal cuboid parts. This is useful when taking advantage of multi-core processing via the Run FDS Parallel action, where meshes can be assigned to individual cores. Read More...

Pick Your Favorite Scenarios with Selective Export

November 17, 2021
Scenarios were previously introduced to PyroSim as a tool to help repurpose assets within a model for various use cases. In the upcoming PyroSim 2021.4, users will be able to select which scenarios get exported before creating the batch file. Read More...
