Pathfinder / Re: Adding symbols for easy export

That sounds like a great suggestion. Can you email to information about the symbols you would like to add as annotations and we can get that in the development queue.

Yes, please see:

Yes, Pathfinder can output the positional data for each agent in the simulation, along with other useful information from each point in time written to file. Please see the User Manual for more information.

Do Annotations do what you want?

It should be the 25th Vent down from the top of the FDS input file.

PyroSim / Re: Problem importing dwg-files

Did you import the version of CAD file after moving the geometry closer to the origin and confirm in PyroSim that the geometry is close to 0,0,0 there too?

This might be related to a change in FDS 6.7.6.  See if thickening the geometry resolves the issue.

Pathfinder / Re: elevators

The number of occupants in an elevator depends on the 'Nominal Load' setting.

Please see if modifying this value gives you the elevator loading that you are expecting.


It is difficult to tell what is happening from this screenshot.
Please send your model to and we will take a more detailed look.
Also, please see our support page for more information

You might be interested in this newer feature.

You could import a vehicle and hide the 3D model of the person inside the model in a seated or laying down 'animation'.

Here is a fun video and I've linked to the file that I used to make it.

Note: the tour is in the pfrv file, so when you extract the files and run the Pathfinder simulation, the pfrv file should open and let you play back the tour.

We don't know anything about how Exodus works, you would need to contact the development group for that product for answers to your question.

The details of the input file format are in the Pathfinder Technical Reference Manual.

Pathfinder / Re: Occupant smoke slowdown

No, that tutorial is old and the new automatic feature replaces that manual process.

Pathfinder / Re: Combining Files in Pathfinder
« on: May 21, 2021, 05:30:58 pm »
Yes, we have added in some limited copy/paste support in Pathfinder from one model window to another.
We still have 10 or so issues to resolve for complete implementation, but it is an active work in progress.

Please report to if you try this feature and it doesn't work as expected.
