What version of AcuSolve are you using? Also, is it possible to upload your input file? This error typically means there is something drastically wrong with the model set up somewhere.

Do you still see the error if you set the turbulence model to Spalart-Allmaras?

Altair Forum User

yeah when i Change Model from spalart allmaras to K omega I am getting same error

Filip Klouda

Hello,

I think K omega can be used only for steady state analysis.
