CST - Aborting of thermal simulations

Hello,

in the moment i have often a abortion of thermal simulations. Respectively a error message appears.

expiration:

  1. Tetrahedral mesh in Low Frequency Simulation
  2. Thermal Loss calculation as field import for thermal simulation via CHT Solver
  3. Thermal simulation with CFD mesh

Maybe there is a dependence to the amount of mesh cells in the thermal simulation?

Thank you very much for your support and help :)
