Hello everyone,


So we are in need to ansys 2019 as well for the computers we run on. Ansys 2020 and 2021 run fine on Rhel 8.6. We understand that 19.3 does not support Rhel 8.6, however we were able to get the required 7.6 libraries and install them to another directory and then add them to LD_LIBRARY_PATH. Now most things in Ansys work except for workbench mechanical and workbench mesh. Workbench mechanical freezes during geometry attach and these error pop in terminal:

However, sometimes it will load, but then freeze when we run mesh, it will show a green checkmark around mesh in the tree, but become unresponsive, the mesher progress bar doesn't even show up either. We are wondering why everything but workbench mesher works? Is there additional pre-requisite packages we are missing?

Thanks for any help!

It seems like ansys mesher is the one that's failing to run
