Hi Arjun,

Ubuntu is not officially supported. Do you have other OS that you can run this on ? Here is the list of them

you may also have graphics issue. Here is the list of supported graphics card

That said, what you can try at the moment is to do this

set these two environment variables

LIBGL_ALWAYS_INDIRECT=1

LIBGL_ALWAYS_SOFTWARE=1

then launch Workbench with 

/usr/ansys_inc/v180/Framework/bin/Linux64/runwb2 -oglmesa

Thanks,

Win
