Failed simulation with Evac

[MaWo80]

Hello,

i designed a building in Pyrosim. The fire simulation works fine. But now i want to make a evac simulation in in the same simulation and i always get this failer log:

Does somebody know this falure or what i can do ?

[Charlie Thornton]

I'm not sure. It's possible that something in FDS+EVAC has changed and PyroSim hasn't kept up. What version of FDS are you using? (e.g. "whatever version came with PyroSim 2010.2", or "I installed a custom version of FDS, it's 5.5.3")

That warning about DEFAULT_PROPERTIES also seems worth checking out. When you look in the Record View, do your PERS namelists have the DEFAULT_PROPERTIES value set?

[MaWo80]

Hello ,


I use Pyrosim 2010.2.0111.  FDS is in Version 5.5.3.  I can´t find a newer version to install. on the nist website there is a version 5.5.3a but this version don´t run with pyrosim.

2nd) person "default_PROPERTIES='Male'/" thats it.

I still don´t know how i can solve this thing. Are there too muich meshes ? I Have a quadcore cpu intel i5!

When trying to reproduce the problem you mentioned, I found something similar but not exactly the same. I started with the single-mesh "roomfire" example problem and split it into two fire meshes and two evac meshes (and configured it for evac with a couple occupants). This worked fine when run in the normal (serial) way, it also worked fine in parallel with OpenMP, but when I tried to run in parallel with MPI I got this:

I think there might be a problem with the way FDS+EVAC looks up the evacuation mesh data when all of the meshes have been assigned to different processes by MPI. However, that wasn't what you were seeing. I wasn't able to reproduce the PERS warning or your particular crash. Can you post your PSM or FDS input file?

I think the problem with this scenario is that EVAC, as far as I know, doesnt support MPI yet?

Updated: Copied from EVAC manual:

"The present version of FDS+Evac does not fully support parallel CPU calculations for
the evacuation part. If a FDS+Evac calculation needs too much computer memory, then
the user must increase the amount of available memory. This may require switching
from a 32 bit to a 64 bit operating system, because the evacuation meshes can not be
distributed over many different processors/computers unlike the FDS fire meshes using
the MPI version of the FDS executable."

2nd) person "default_PROPERTIES='Male'/" thats it.

I also get the error message: "PERS globals no DEFAULT_PROPERTIES given".
The simulations still seem to run allright.

[Ratas]

I think the problem with this scenario is that EVAC, as far as I know, doesnt support MPI yet?

So Pyrosim seems to assign all the meshes to different processes, resulting in this error?
If I understand correctly you should be able to run the fire meshes parallel, while EVAC is running on a single process simultaneously.

[Charlie Thornton]

Fair enough. Thanks. I've added a note to our issue tracker.
