PyroSim PyroSim Improvements


Users can define multiple enabled/disabled object sets as a Scenario, activate a single Scenario to quickly switch your model, and create a batch file to automatically run multiple Scenarios in sequence.

Vent Area Calculator

Vent Area Calculation
Vent Properties dialog

Surface area is now calculated and displayed on the Vent Properties dialog.

Pathfinder Pathfinder Improvements

Escalator Preference

Occupants may prefer to Walk or Stand on escalators. Occupants who Stand can be given a preference for a left or right side. Occupants who Walk will navigate around the Standing occupants.

Escalator Preference
Escalator Preferences are available in the Edit Profiles dialog.

PyroSim Results Pathfinder Results Results Improvements

CSV Imports

CSV Imports in Results
View imported CSV files in Results.

CSV files which are automatically generated from PyroSim and Pathfinder, in addition to other CSV files, can now be imported and viewed directly from Results.

Social Distance Disk Representation

Social Distance Disks
View Social Distance discs in your model.

Social distance disks can now be displayed as half of the social distance radius, so that disk overlap directly indicates occupants are too close (assuming uniform social distance).

Half Social Distance Disks
View Social Distance discs with half the radius to show where individuals are unable to stay adequately separated.

This cleans up the display of information when many occupants are near, while also more clearly presenting the intended effect.
