Hi,
I have been using Ansys ver 11.0. I have created a batch file that I see to be correct but for some reason Ansys freezes up and does not complete the simulation. The other input files are all in the one directory so I really cannot seem to find a proble. I was wondering if anyone knew of a reason why this kept happening and maybe offer a solution. Please help. Below is the batch file i have created.
