When you installed 2021 R1 it may have changed something in the ANSYS files that is affecting ANSYS 2020 R2. It's most likely related to the libs since it mentions libstdc++.so.6.nThe LD_LIBRARY_PATH=/ansys_inc/v211/Framework/bin/Linux64/Mesa#export is set to 2021 R1. Can you delete this or set to the 2020 R2 and see if this resolves the problem for 2020 R2 since it is supported under this OS and, if so, you will not be able to run 2021 R1 on this machine without updating the OS. nMarch 4, 2021 at 9:24 pmdb_ikSubscriberThank you for your comment, I applied as you recommanded but the version 2020R2 is also not working.nAt the physical workstation location, all versions are working okay, but remote access causes the issue.non another machine, fresh restarted the OS and cleared the caches by deleting .ansysnit starts the mesh editor ONLY ONE TIME with following statement as[Info] Server started at ws://0.0.0.0:0 (actual port 44911)nHowever, fails to start the mesh editor no the next opening mesh.nRegards,March 5, 2021 at 1:29 pmMatt MadoreAnsys EmployeeWhat is the version of VNC you're using?
