Writing initial trn files for cases with complicated call backs and topology may cause the CFX Solver to crash.

When writing a trn file at the start of the run, that is during initialization, in a parallel calculation with complex call backs and topology, the Solver might crash with the following error message:

Length of variables list is not consistent in parallel. Routine GET_VARLST called from routine Write_Soln_ZifCs.

This is caused by the call backs only being evaluated on some partitions, and communication going astray.

It may be possible to modify the topology of the call backs to ensure that evaluation is needed on all partitions. Alternatively, different partitioning methods may help.

ANSYS CFX Release 14.5. A custom executable for ANSYS Release 14.0 is available on request.
