[MNMK]

Hi,

I have a simulation model that includes Rotor and stator. I simulated the model once with simple Geometry( firstly, I ignored other components in my model) and it worked well. The second time, I had other components in my model which increased my mesh number to 21 M. This time I have got the error. See below:

| Topology simplification is activated with the following |
| restrictions: |
| |
| - Mesh regions referenced only within User Fortran and NOT |
| in the command file will cause the solver to stop. |
| - The solver will stop during any "Edit Run in Progress" step |

I use a cluster and also 32 cores. I have tried to increase the memory size to solve the problem but it has not worked. I am grateful when somebody helps me to solve the problem.
