[fds-smv] Instantaneous time output with SLCF files?

[fds_buoyancy_cavity]

Hi all,

I currently use FDS to study buoyancy-driven flows in cavities, with a
hot and a cold wall driving the flow. I have done quite a few
calculations now on my FDS model and have only used SLCF outputs
thinking that they would cover an entire plane instead of discrete
points of the DEVC namelist. However, having done so I have a problem
now because I want to calculate temperature and velocity fluctuations
in this highly turbulent flow (i.e: T=f(t) and V=f(t) data), and the
fds3ascii.exe program only yields mean values for the entire plane.
Therefore my question was if I could EXTRACT temperature and velocity
values against time for discrete points CONTAINED in the slice files
instead of having to do the calculations again with DEVC outputs...

Thank you.

The format of the SLCF file is in the Appendix of the FDS Users Guide.
I suggest you write a little program to read it, preferably Fortran,
but something like Matlab will work if you remember that Fortran
attaches a 4 byte header and trailer to the records.

A Matlab script for reading slices was discussed in previous thread:
http://groups.google.com/group/fds-smv/browse_thread/thread/97bbaaf790642836/f9c8f975d43c7a68?lnk=gst&q=slread#f9c8f975d43c7a68

(or search slread from this site).

Simo,

I committed slread.m to the repository in Utilities/Matlab/scripts/.
I tested it and it seemed to work great. If you've made improvements
please update.

Thanks.
Randy
