Hi Luis,nThis could be a graphics issue as well although it's hard to tell why it's specific to your user account.nFor stand-alone Fluent, in Fluent Launcher -> More Options -> Environment , you can try adding the following.nFLUENT_LAUNCHER_OPTIONS=-driver x11nsee if this makes any difference.nnFor Workbench-Fluent, try the following (you can also add the same thing above in this Fluent launcher)nexport LIBGL_ALWAYS_INDIRECT=1nexport LIBGL_ALWAYS_SOFTWARE=1nexport LD_LIBRARY_PATH=/v###/Framework/bin/Linux64/Mesan/v###/Framework/bin/Linux64/runwb2 -oglmesanNote: You have to replace /v### , with the actual installation path and version number.n
