ANSYS Crashing
 

Hi everyone :)

Recently I have started FSI . I have completed the geometry part. When I was doing meshing part ( I am using Fluent Meshing - ANSYS 16.0) , When I selected all the surfaces of my model ( approx. 5000 ) and then when I right click on the selected objects, the fluent windows closes all the time. Anyone know why is this happening?

I have tried following.

I have updated my computer driver from old to new ( assuming that display driver problem) but Could not solve the issue.

I have tried with my university system ( assuming that cracked version of my ANSYS problem) but same happening with my Uni system's license.

Please explain clearly what might the solution for my problem. Thanks a lot in advance :)

I have attached picture. Please find the attachment too.
