Since VTT's FDS+Evac has been incorporated into the official FDS, I
wonder if it's going to be more useful to include the Evac
documentation as part of the official FDS users guide. It would
minimise the need to maintain 2 separate documents.

In the interim, will be the user's guide for FDS+Evac be availble for
download from this official FDS site?

We will keep the documents separate. There are various reasons for this that are not swayed by convenience... Sorry.  But, there will be links added to the FDS website that will take you directly to VTT's web pages about FDS+EVAC.

Thank you for the suggestion,
-Bryan

Bryan's message has a hint of intrigue ... Actually, there is a good
reason for keeping the Evac documents separate -- the Evac routines in
FDS were developed primarily by Timo Korhonen of VTT, Finland. Glenn
Forney and I helped to put the necessary "hooks" into Smokeview and
FDS, but the heart of the Evac algorithm was written by Timo, and
because of this he needs to have total control over that part of the
code and its documentation. NIST and VTT have their own respective
review processes, and we thought it best that the Evac routines be
reviewed and maintained by VTT. However, Simo Hostikka of VTT
continues to work on both the fire part of FDS and to some extent the
Evac. Glenn and I still need to do a few things to improve the Evac
part.

HEllo,
Maybe it's a little bit weird question but where can I download fds
+evac installation file? I checked the VTT site without any success,
there is a ling but does't work. Maybe I doesn't understand the idea
of EVAC and there is a way to "upgrade" my fds to FDS+EVAC version.
Thanks for any help.

Hi,

EVAC is still implemented in FDS... There is no special download

Here you can find more information and the link to the FDS+Evac -
Technical Reference + User's Guide (FDS 5_RC6, Evac 1.10):

Hi!

The FDS+Evac web page at www.vtt.fi/fdsevac/ is not up to date. I have
been
too busy to update it. Most of the example files on that web page are
for
the old Evac, which was fds4 based. Some fds5 based example input
files you
find in the 'Valid&Verif' page, there at the bottom of the page is a
link
to the IMO test cases. These are good example input files for the
present
FDS+Evac. (Note: Some of the FDS input might be out of date, because
these files are a couple of months old...)

And see the previous comment by Gregor, i.e., follow the link given
there.

Hello All!

I would like to use FDS5 like EVAC. It works well. But If I would like
to use it in mpiexec (paralel) mode it doesn't work. I have read in
FdsEVAC user's guide that fds and evac can't work together in paralel
mode. If somebody knows about it, please write some things.

This is something that we are working on.

FDS+Evac, i.e., the evacuation subroutine, is now only called
from main.f90. There will not be a true parallel version of
FDS+Evac very soon. First there will be a parallel-fds version,
which will write the CHID_evac.fed file for the evacuation
calculation. This will be out there during spring 2008, hopefully.
Then you can do a parallel fire calculation and after this
use the fire information in the evacuation part,
which is run using a single processor. There is no need to
run fire and evacuation at the same time, because running
fire first and the running only evacuation is just the same
as running both at the same time. The fire <==> evacuation
data is transfered via the CHID_evac.fed file. And for now,
there is no two-directional coupling in the calculation,
i.e., the data flow is fire ==> evacuation.
