Hi,

i'm doing a coupled cfx/thermal & structural calculation of a water cooled mold in CFX/Workbench.

After evaluating cfx calculation, i setup up the thermal model and imported the surface temperatures from the cfx calculation into the steady-state thermal model without any problem.

But when starting the solving procedure, workbench stops with following error:
*** ERROR *** CP = 207.328 TIME= 17:05:27
An unexpected error ( SIG$SEGV ) has occurred... ANSYS internal data
has been corrupted. ANSYS is unable to recover and will terminate.

Unfortunately i found no hint for this error message in the help or in the forum, therefore it is a little bit tricky for me to get rid of the problem.

Does anybody knows this problem?

Best regards,

I've met this problem before.... but maybe it would be a start to check if you've choosen the correct faces where your CFX Temperature are applied to.

also, make sure your CFX Mesh and the mesh in the thermal analysis are identical.

Dear Li,

thanks for your reply.

Meanwhile i contacted also my ansys distributor, and i was told that the occured error is mainly related to memory problems in Ansys12. There is no exact workaround, because the error is intermittent. Maybe a different mesh will already solve the problem.

Obviously this kind of error occurs with Ansys12 (Workbench2) and not with Ansys11 (Workbench11). So i took the generated ds.dat from Workbench2 and solved it with classic Ansys11 without any problem. After that i read in the results file in Workbench2 for postprocessing. Nevertheless, even if this workaround helps me to solve my current problem, it would be quite annoying if this happens more often in the future.

Maybe the next Ansys release will solve the problem.
