I have been working with Ansys Mechanical (not APDL) to do acoustic simulations with the acoustics ACT for a little while now . I use Ansys 18.0 and the Ansys 18.0.2 Acoustics ACT.
On my own system everything has been working perfectly fine. As I have less time left and would like to do simulations for higher frequencies, I tried to do the acoustic simulations on the HPC/LSF10 of my university. Regardless of whether I loaded the Acoustics ACT or not, when I open the Design Modeler or Ansys Mechanical, there seems to be something going on with the graphics: My geometry is flickering in the viewer, when I hover with my mouse over the geometry it disappears and the boundary conditions, which I have set up before during the simulations on my own system, are somehow not recognised. Even though I have selected faces for the boundary conditions, and in the graphics view the faces are colored blue, the boundary conditions still have a question mark ''?'' next to them in the tree on the left instead of an OK mark.
I have done a little digging and it might be how the HPC/LSF10 environment is set up, how Ansys Mechanical is launched from workbench and something with the shared libraries. I thought of starting Ansys Mechanical right away (not APDL), but I can't find out what the command for that is and if I was able to do so, how I would load the Acoustics ACT. Do you perhaps know what the problem is and how I can do the acoustics with Ansys on the cluster?
PS. The same problem is observed whenever Ansys Mesher is opened.
