This is a problem with the VTK libraries that MFiX uses. If you search Google for “missing GL version” you will find a number of matches, relating to MFiX and other software that uses VTK such as Paraview. There are also some previous questions on this forum.

I’m afraid I don’t have a simple answer, but it would help to know exactly what packages are installed, and what graphics card you have. Please post the output of “conda list” (with the mfix-22.1 environment active).

Can you run “glxgears” on this machine? That’s generally a good test of a working GL installation.
