This page describes how to run CFX, which is part of the Ansys suite of programs.
To run Fluent you need to be added to the
ansys group and have set up your floating licence. Please refer to:
You will only run CFX in batch mode. Slurm batch scripts need to load the appropriate
cfx module and then launch the program. When running on Cray systems, there are additional runtime arguments that need to be passed. Listing 1 shows an example.
When running the program, use a sensible number of partitions, which will depend on your individual model as well as the number of nodes you are running on. Make sure the overlap of partitions is small, and aim for less than 10% overlap.
