Hello everyone, I'm trying to run a Transient Blade Row of a centrifugal pump and everytime I try starting the sim, I get this error:

+--------------------------------------------------------------------+

Details of error:-

Error detected by routine PEEKCA
CDANAM = CPERIOD
CRESLT = NONE

| An error has occurred in cfx5solve: |

| The ANSYS CFX solver exited with return code 1. No results file |

+--------------------------------------------------------------------+

End of solution stage.

+--------------------------------------------------------------------+
| The following user files have been saved in the directory

I already tried setting it as a large problem, switching to single instead of double precision, setting the memory allocation to 2 and to maximal and running it in serial instead of parallel. I tried all parallel run modes, changing various parameters in the simulation setup that could lead to a changing demands on the memory and changed the interface from the warning to "Transient Rotor Stator", just to see what happens. Nothing of that worked.

I'm looking forward to your help!

Edit: Could this possibly be a problem with the meshes?

You have a setup error where the period cannot be calculated. Review your model can compute the period for the transformation you have activated, or not have defined.
