[Touré]

Hello everybody,

I have Ansys 18 and Ubuntu 16.04 LTS installed on my computer. I can start a ANSYS Fluent project in Workbench. I can draw a geometry with the ANSYS Design Modeler. I can create a good mesh with the ANSYS Meshing module for the first time it's launched. Whenever I exit ANSYS Meshing, I can't go back. I can not edit the mesh again because when I try to launch the ANSYS Meshing module for a second time the ANSYS Meshing window pops-up, shows the drawing and freezes. The workbench window task bar gives the message: Starting Meshing...
I can keep on waiting but I won't have any error message that is why I do not know where to beginning for solving the problem. The detailed message that I get when do a right click on the Mesh and chose REfresh is below.


Thank you in advance for you support.

I have the same problem, Ubuntu 16.04, Ansys 17.1

[divergence]

This might be slightly silly thing to write but have you checked that the license is available? Is there any meshing processes running according to the process list? Does the DM file open properly?

I have a hunch that Ansys has been putting Windows on a pedestal at Linux's expense for quite some time now. The modern revisions of workbench and its programs might not be completely compatible with linux, which is a crying shame. I don't use DM or Meshing in a linux OS but I have noticed that the linux Fluent does have some embarassing bugs that are missing from the win version of the program.
