Fire + Evac -Fanthom obstructions #307

Closed gforney closed 9 years ago

gforney commented 9 years ago
Please complete the following lines...

Application Version: 5.1.4
SVN Revision Number:1437
Compile Date:14, Mar. 2008
Operating System:Windows XP

Describe details of the issue below:
When I combine fire and evac, I noticed that my obstructions (obstacles) 
double in height.  I have studied the evac-example2a and duplicated 
similar code lines but I am still unsuccessful.  Timo, could please have a 
look at the attahced input file.

Thanks.  Daniel

Which version of FDS are you using? I tried your input file:

ERROR: PART_ID for PROP    3 cannot refer to MASSLESS particles

And could not run the case with the version:

Fire Dynamics Simulator

Compilation Date : Wed, 09 Apr 2008
Version          : 5.1.4 Serial
SVN Revision No. : 1548

I took out the SURF_ID='EXHAUST 1' etc control logics and then the 
case run.

Next check: I took out the fire mesh line (deleted the "&") and run
just in the evacuation mode and now problems in the geometry.
The (evacuation) OBST were 1.2 in height as they should be, see
the evac-mesh line:

&MESH IJK=216,216,1, XB=-28.0,28.0, -28.0,28.0, 0.4,1.6, EVAC_Z_OFFSET=1.0,
      EVACUATION=.TRUE., EVAC_HUMANS=.TRUE., ID = 'FF1stFloor' /

Here you say, that the z is from 0.4m to 1.6m, the mid point is
then at 1.0m ==> EVAC_Z_OFFSET=1.0, so the soldiers will have their
feet at the level z=0.0m.

Ciao,
Timo

Now I updated my FDS version (was on a conference trip
last week...):

 Fire Dynamics Simulator

 Compilation Date : Sun, 20 Apr 2008
 Version          : 5.1.4 Serial
 SVN Revision No. : 1593

Now no "ERROR: PART_ID for PROP" problem anymore. But the simulation seems
to run as it should. The evacuation geometry seems to be ok, 0.4m - 1.6m as
defined on the evacuation mesh line.

Timo -- I fixed the bug related to PART and PROP. I plan to release FDS 5.1.5 this 
week, so let me know if there is more to do on this case.

Well, the fire and evacuation OBSTs are shown in Smokeview.
The evacuation OBSTs have the same z values as the corresponding
evacuation mesh. This is the reason why you see too high OBSTs
in your Smokeview pictures. There are no easy cure for this.
You could change the color of the OBST in the evacuation mesh,
see the discussion forum topic " Hiding EVAC MESH and objects..".

I'm not going to change this right now. In the future it might
be possible that the Smokeview is changed so that you can easily
choose only fire meshes, only evacuation meshes, or both. But this
is not on the TO DO list yet.
