FDS+Evac: Problem with EXIT

[nadhifunosekai]

Hello,

I am a beginner in using FDS, especially for evacuation-related scenarios. I have encountered an issue in my simulation that I have been trying to resolve for the past three days, but unfortunately, I am still getting the same error.

To provide some context:

1. As a test, I created a building geometry using Blender.
   

2. I added only one EXIT door on the west side of the building.

3. However, when I run the FDS script, the simulation stops abruptly midway, and it does not complete.
   

I initially suspected that the issue might be related to the placement of the EXIT, but after adjusting it multiple times, the problem persists. If necessary, I'll share the .blend or .fds files for further review. I would greatly appreciate it if you could take a look and help me identify what might be causing this issue.

Thank you for your time.
Best regards,

[Vojta-Salek]

Hello, please provide your FDS input code.

Also, be aware that FDS+EVAC is no longer supported. However, someone might be able to provide assistance. The developers will probably not be able to help.

[nadhifunosekai]

Actually, I suspected that might be the case. However, in a previous experiment (before modifying the model/script), I was able to run the simulation, although the agents still couldn’t find the DOOR/EXIT like this ..
