Cfx_solver_full_university_limit

Hi every body
I'm trying to solve a problem involve moving mesh. all the things is good and solution with Cfx solver manager done but at the end of run solver terminated with error (Note Solution is converged!!) and this message show:

Feature CFX_SOLVER_FULL_UNIVERSITY_LIMIT does not exist in the ANSYSLI pool.

An error has occurred in cfx5solve:

The ANSYS CFX solver has terminated without writing a results file.
Command on host tahpc (TAH-PC) exited with return code 0.

What is it??What can i do?
Thanks.

I suspect the license error message is not important. If the run went it must have got a different license.

I think the real error is the host name tahpc died somehow. Probably some sort of network problem.

Thanks ghorrocks
The run went and make .trn files but the .res file is not available, i can't open .trn files . this error message occurs in cfd-post:

ERROR
Error reading file 'C:\Users\OMID\Desktop\NNNNN\2DWall\Fluid Flow_011\4.trn':
Error reading number of domains (G/NZN).

i examine it in various Pc and this error occurs.
What can i do?

trn files are usually set up to contain the minimum to show the time step. This means they do not contain the mesh information and need a res file to define the mesh. Without a res file your trn files are useless.

You can setup trn files to contain enough information to be loadable by themselves, but of course the file size becomes much larger.

But the root problem is something is stopping your results file being written. This is what you should fix. Maybe you ran out of disk space, maybe a network glitch, maybe the distributed parallel is not set up correctly.

I suppose until the server gets back up and you really want results, you could probably write out .bak files every [x] iterations. CFD-post can read the .bak files. But watch out though, these files can get large (in the GB size). Make sure they're the full backups.

You should not use bak files for transient runs. Use full trn files instead.

Thanks mahill and ghorrocks.
