Autodesk Simulation CFD

[#1]

I'm performing an analysis on a simple liquid cooled cold plate and until recently I have had no issues with the solver and have gotten good results. I have now moved to a new faster workstation and upon running any of my old models the solver exits unexpectedly without any warning (no crash, the "go" button simply changes to "stop"). I looked into the log file and found the following messages :

 [16:26:37] Solver for <filename> exited at Fri Jan 25 16:26:36 2013 on <mycomputer> with status = 0 and code = 255
[16:26:37] Unable to inject glr
[16:26:37] Unable to inject gls
[16:26:37] Unable to inject glv

I am still using an old version of CFDesign so hopefully one of the old CFDesign support guys like Royce can help me.

Thanks,

Dave

Hi Everyone,

First of all, thanks for nothing. I managed to finally solve the problem on my own.   

If anyone ever comes across the same issue where an older version of the solver will not run on a newer Xeon workstation with more than 8 cores, here is the solution. Simply go into your bios and reduce the number of CPU cores down to a total of 8 (in my case since my workstations all have 2 CPUs, I set the maximum to 4 cores per CPU). I tried this fix on a number of 12 and 16 core Xeon E5 workstations and it solved the problem in every case.
