The environment for GaussView 6 is automatically set up when loading the gaussian 16 module e.g.
$ module load gaussian/g16c01
For more details on using modules see our software applications guide.
GaussView is then invoked by typing the following command from an X-window session:
$ gv
If the above ommand is generating error or issue, use the following command:
$ gv -soft
The -soft
flag uses software opengl rendering instead of hardware and your issue should be resolved.
If you are using XQuartz on macOS to run GaussView, you need to configure XQuartz to allow indirect GLX contexts. You can do this by quitting XQuartz, then in the macOS Terminal application run:
# New versions $ defaults write org.xquartz.X11 enable_iglx -bool true # Old versions $ defaults write org.macosforge.xquartz.X11 enable_iglx -bool true
