Ansys
=======

Ansys can be enabled for use within your submission script (or interactively) with the following commands:

.. code-block:: bash
    
    flight env activate gridware
    module load apps/ansys

Here is an example of a full submission script for Ansys Fluent (provided by Assistant Professor Fabio Malizia):

.. code-block:: bash
