ANSYS must ALWAYS be run using torque. You can run ANSYS in an interactive mode via a GUI that is called the launcher, or in a non-interactive (batch) mode. In both cases you start ANSYS using the qsub command.
Running ANSYS interactively (using the launcher)
You desktop PC will act as the X-server for the ANSYS launcher. Exceed is the ACCC-supported X-server package. However, you are not required to use Exceed; there are other Window-based X-server packages that will work just as nicely.
