  3. In VNC Connect + VirtualGL remote graphic environment, standalone Fluent can find and use hardware accelerated graphic driver by launching Fluent with vglrun (e.g. vglrun /ansys_inc/v192/fluent/bin/fluent). But when Fluent is launched from Workbench which runs with vglrun (e.g. vglrun /ansys_inc/v192/Frameworks/bin/Linux64/runwb2), cortex process (cx1920) is not listed in nvidia-smi output, and VGL logo doesn’t show up in Fluent graphic when VGL_LOGO=1 is set, while other Workbench application process, such as the “mono AnsysWBU.exe” process can be found in nvidia-smi output and VGL log appears in DesignModeler, Meshing or Mechanical graphic window. How to enable Fluent launched from Workbench to find and use hardware accelerated graphic driver in VirtualGL remote graphic environment?

      Option #1: Set below environment variable in the Environment tab of Fluent launcher window: CORTEX_PRE=/bin/vglrun For example: CORTEX_PRE=/opt/VirtualGL/bin/vglrun Option #2: Set below system environment variable before launching Workbench with vglrun For C Shell: setenv CORTEX_PRE /bin/vglrun For Bash Shell: export CORTEX_PRE=/bin/vglrun Similar solution may also apply for OpenText Exceed onDemand remote graphic environment, which need a ssrrun command to achieve server-side rendering for accelerated graphics performance.
