Hi Pouyan,
Do you get any errors when your model crashes? Do you face this crashing error with every model or with the specific model only?
Have you tried to clear the %appdata% and change the name ".Ansys" in the %temp% file? I have seen that some users have resolved this type of issue by resetting the ansys through %appdata%.
Does the mechanical window close after crashing or does the WB window also close?
Regards,
Sampat
