@Win, looking at the screen shot, this ANSYS 19.2 Student license has a licensing issue, it is trying to obtain a Mechanical Enterprise license from a license server.

@baswaraj123,  Is there a reason you need Release 19.2?  If not, you could try installing ANSYS Student 2019 R2 and see if you can run your model there. Note that if you save your model in 2019 R2, you won't be able to open those files in 19.2, so create an archive of the model in 19.2 and put that file aside before you install 2019 R2.
