[esp-r] Re: CFD analysis problem

[Andrew Cowie]

Hi Kostas,

How long is the simulation taking? If it is taking a suspiciously short time you may be getting NaNs creeping into the CFD, I have had frequent problems with this in the past and it does tend to confuse the res module. Check the monitoring output to ensure this is not happening.

Also, you are right in that you need the "libc" file for the CFD results. The "XYZ.res" file is entirely different.

Hi,

I have run the example model CFD_room1.cfg. The simulation ended OK and
generate an 12Mb file (libc, activate the CFD solver) along with 297Kb
file with the normal results (CFD_room1.res). I can analyse the .res
file fine. When i go to CFD, enter the file name libc the program
response "No CFD zone detected". I try the res file but the following
error pup up "CFD header fault. Cannot read file".
What i am missing here?

Thanks in advance,
Kostas Gompakis
