KNOWN ISSUE: Solver-pcmpi processes left running on windows after negative volume element error


SYMPTOM:
In moving mesh cases which are run on windows machines in parallel using PCMPI, the detection of a negative element normally results in the solver stopping cleanly, may cause the run to hang, with the solver reporting that the master process has completed but slave processes still running.

PROBLEM:
This problem occurs only when a negative element has been detected and the solver attempts to stop cleanly. In this case, each process attempts to open and close the solver job file (an internal file used to echo job information during the calculation), and it is this action that causes the hang on windows.

The problem does not occur in serial or on non-windows platforms.

WORKAROUND:
No workaround is currently available.

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