hi i have been looking for the openMP environment dialogue box in pyrosim but cant find it. it doesnt say how to open it in the user manual. can anyone help me?
kind regards

Hi everyone,

I hope you are all well. I have two questions. I have 3 meshes running in a simulation. I have no idea how many cores my simulation is running on. Question 1: Can anyone tell me how to tell how many cores my simulation is using (see attachment 1)?  I have a computer specifically for pyrosim and it is only operating at 46% performance (see screen shot) Question 2: can anyone tell me how to get my computer to use more of its "power" ? It seems like if it was operating at twice its performance, let's say 80%, it would do simulations a lot faster.

kind regards,

You should either change the backing setting or edit the geometry to work with the 'exposed' backing type.

Please email the Pathfinder model to so we can review the issue.

I have an issue, where after almost everyone has evacuated the building, a handful of people run around, go up a set of stairs, run to another and go back down, run around some more.  It's adding 5 minutes to the evacuation time.  It's like they're children playing tag (no I have no children in the model).  How do I keep them from going back up the stairs, or running around seemingly aimless?

I can't post the file because the project is confidential.

Any help would be awesome.  Thanks

I get the following warning message, not sure if it affects the accuracy of the modelling if I choose to ignore it.

FDS uses rectilinear grids in it's calculations. When using rounded geometry, it is important to verify that PyroSim successfully rasterizes the tank into obstructions free of gaps. See the section about Angled Geometry in the PyroSim User's Guide to learn more about how you can test that proper grid blocks have been created by PyroSim before running your model.

I am doing a project which is based on domino effect analysis of fire on atmospheric tanks. I have made a CAD geometry and imported in the PyroSim. fire on one tank will give heat flux traveling to other tanks. I just want to know will FDS give reliable results with such geometry in PyroSim. How will FDS generate mesh for such circular geometry?

Thank you for all of these great suggestions!  I will convert them into feature requests in our system.
