License set-up for using legacy Ansys modules

License set-up for using legacy Ansys modules#

Before running the old versions of Ansys module (older than 19.2) for the first time, there is a per-user setting that chooses whether commercial (default) or academic licenses should be used.

For research purposes you should normally be using the academic licenses, unless you are untertaking commercially funded research.

Check with your supervisor if you need clarification on this.

You will need a SSH connection with X-forwarding enabled to configure this setting. For more information on how to connect to the ARC systems and to enable X-forwarding visit the Logging on page.

If you have not already done so, set the license server and port using the details provided by your supervisor:

$ export ANSYSLMD_LICENSE_FILE=<port>@<host>

Next, ensure that you have the Ansys module loaded for the particular version you wish to configure its licenses, e.g.:

$ module add ansys/17.1

For legacy Ansys versions, you need to launch the license administration interface. The simplest way to do this is to start cfx:

$ cfx5

and select Tools -> ANSYS Client Licensing Utility from the menu.

This will present you with the following window:

Configuring a license for Ansys using the license manager.

Select “set license preferences for user abcxyz”

In the next window, select the product you wish to configure (e.g. 12.1)

Selecting the right license preferences.

In the next window that appears, select the radio button that says Use academic licenses:

Finally select the academic license option.

Select OK, then exit the license manager.

This will configure Ansys (both Fluent and CFX) to use Academic licenses for all future use.
