Connect with ssh -X/-Y or via VNC to have graphics enabled.

There are, currently, two versions of VMD available on CC clusters:

$ module avail vmd
...
------------------ Compiler-dependent avx2 modules ----------------------
   vmd/1.9.3 (L,vis)    vmd/1.9.4a43 (vis,D)

The default version is 1.9.4a43. To use it:

[name@server ~]$ module load vmd
[name@server ~]$ vmd

This should VMD graphical windows.

You can also specify the version if you want to use the older one:

$ module load vmd/1.9.3
