I have just started using pyrosim and FDS, i have just created a the model in pyrosim that i wish to test, however when run the FDS simulation the following error message is displayed in the dialog box,

Starting FDS: C:\Program Files\PyroSim 2010\fds\fds5.exe...

Unfortunately, that particular error message conveys very little information. It tells us that the FDS process has encountered an (unknown) error and exited. This is relatively uncommon and I don't know of any issues with the current version of FDS that would lead to this problem.

To move forward, someone needs to delete parts of the model until it is reduced to the simplest possible form that still produces the bug. Once that's done we can find a way to work around the issue and we can send the reduced example to the FDS issue tracker so the team at NIST can address the bug in the simulator.

If you email your PSM file to we would be happy to help.
