Visual Improvements in Results 2020.5

November 2, 2020
Since introducing our Results application which combines PyroSim and Pathfinder output into a single workspace, we have continued to improve the visual realism of this package. Our users report that improvements in rendering smoke, textures, and occupant animation not only give their work a more professional look, but also increase the clarity of their findings. In the 2020.5 release, we will add several new features to deliver even better modeling output. Read More...

Social Distance Improvements in Pathfinder 2020.3

August 7, 2020
Pathfinder 2020.3 further enhances the user's ability to model social distance behavior as a method to address pandemic safety. Social Distance has been completely separated from Comfort Distance. Now, rather than Enable Forced Separation in the Simulation Parameters (retained in 2020.3 for legacy files), Social Distancing has its own selection field in the Advanced tab of the Edit Profiles dialog. With this recent development, occupants exhibit less "jostle" or "jitter" while smoothly and effectively maintaining distance. Read More...
