Problem with running FDS and EVAC calculations simultaneously

[Rajat Joshi]

Hi all,

I am trying to run an FDS file to get both fire and evac results simultaneously, but it doesn't seem to be working in the current FDS version (FDS 6.7.9). It keeps on telling that there's some problem with my MISC line that I am not able to figure out.

Please find below, the fds input file for your reference:

The last version of fds that supported evac was 6.7.7

That input file will not work correctly with the latest code.  Glenn's comment was correct.

But, I can still run fire drills in this version. That means it still supports EVAC.

Yes, I understand that now. I'm sorry for my previous comment; and thank you for making me realise the issue here.

yes, the last FDS version having evacuation is 6.7.7. I have been too busy to make a FDS+Evac in https://github.com/tkorhon1. You can find there the evaucation manual and example/V&V input files. At some point, I'll put there FDS 6.7.7 based evacuation part (= fds 6.7.7. sources including evacuation subroutines) and will update the evacuation part, if there si some need (some bug fixes). But the fire calculation will be FDS 6.7.7, so the fire information that evacuation will use, can not be from some more recent FDS release.

If I have time, I'll make the FDS 6.7.7 version of the evacuation part to read in FDS SLCF-information, so that the more recent FDS release fire calculation data could be read inside the evacuation part. I.e., simplest case is just to give some guidance for the user to add &SLCF namelists to the present FDS release input file. And then I would have some simple parser programme like fds2ascii to translate this data to evauation part (the CHID_evac.fed file format).
