Problem with Ansys 211 installation

    • rainwadj

      I have Ansys 2021 R1 installed on a Linux server, but it won’t run. Previous versions did not have a problem, and the installer for this version completed successfully. Any ideas? See below:

      % /usr/local/ansys_inc/v211/Framework/bin/Linux64/runwb2 

      Unhandled exception caught :

      Which release and version of Linux are you running on?
      Also, check the prerequisites in the installation guide for the version you are installing.
      Does an install.err exist under /ansys_inc
    • rainwadj
      It's installed on a file server running OpenSUSE Leap 15.2 in /usr/local, which is exported via NFS to various clients running CentOS 7.
      No install.err in /ansys_inc
      I don't think I've seen an installation guide. I just ran the INSTALL script as I've done for previous versions, and it completed successfully.

      I apologize for the delay.
      The issue is most likely caused by missing OS library named libpng12 in CentOS.
