Default User fortran error when running CFX-10 in parallel

Hello,

I have a problem when I try to run a problem involving a User Cel function in CFX-10 (mpich parallel). I runs fine when I just run on on machine. The error message in parallel looks like:

+================================================= ===================+ | ****** PROBLEM REPORT ****** | |--------------------------------------------------------------------|

I hvae double-checked that the library path and calling name is defined correctly in CFX-Pre, and that the callingname is in lower case.

Furthermore the winnt library with the dll and other files is available on a network drive that is accesible by all computers in the cluster.

Also I have tried to edit the cfx5mkext.ccl accordingly to the manual by changing the: ext link lib5files = solver-mpichnt.lib from the default value: ext link lib5files = solver-pvm.lib. But still I got the problem.

I am running out of ideas what could be wrong. It is strange that it works in serial mode but not in parallel. If anyone else has come across this, I will be happy to hear if you found the solution.

Best regards CFDworker

Did you re-build your libraries when you changed the 'link lib5files' setting in cfx5mkext.ccl?

In serial mode, the solver always uses solver-pvm.exe.

Yes, I was rebuilding it, and while it was compiling I could see that it was building it for solver-mpichnt. It is a rather strange and annoying problem...

And also as a tjeck, when I had rebuilded it for solver-mpichnt, I got a similar problem (the same error message as in parallel, but now in serial) when I was trying to run serial with solver-pvm (which of course makes sense...)

- But thanks for the suggestion. Any efforts to help out is highly appreciated
