+#### Running ANSYS interactively
+
+1. To use graphical user interface, users need to first setup X11 forwarding. [HOW TO SETUP X11 FORWARDING]({{< relref "how_to_setup_x11_forwarding" >}})
+1. Start an interactie job using srun. NOTE: users need to add --licenses=ansys_research or --licenses=ansys_teaching to the srun command. [SUBMITTING AN INTERACTIVE JOB]({{< relref "submitting_an_interactive_job" >}})
+1. After the interactive job starts, execute "module load ansys/19.2", then run the ANSYS command, e.g. fluent, from command line. The GUI will show up if steps 1-2 are configured correctly.
