ANSYS Fluent is a program capable of carrying out the physical modelling of fluid flow, turbulence, heat transfer and chemical reactions for industrial applications ranging from airflow around an airplane wing to combustion in a furnace, from bubble columns to offshore oil platforms, from blood circulation to semiconductor design and from the design of a clean room up to sewage treatment plants. Special models that allow the software to model combustion cylinders, aero-acoustics, turbines and multiphase systems have made possible the expansion of its field of application.
ANSYS Fluent is a commercial application. Each group wishing to use it at Calcul Québec must provide its own license. For more information, please contact us.
SSH configuration and keys
ANSYS Fluent is an application that is loosely integrated, which means that the user is responsible for starting different processes on every node that is allocated using the batch script. It is therefore necessary to have a means of communication between the worker nodes, and in this case we use SSH.
As no information can be entered by the user during communication between nodes, it may be necessary to generate SSH keys. On certain servers, this is automatically done. To test if this is the case, use the command
[name@server $] ssh localhost
The SSH connection should work without asking anything on your part. If this is not the case, you should generate SSH keys.

Usage on Cottos and Briarée
ANSYS Fluent is also available on the two clusters located at the Université de Montréal but to use it you must belong to a group which possesses a license for this software. An example of a job submission script for a Fluent job on Cottos is the following:
To use the software on Briarée, you just need to modify the value of PPN (12 instead of 8) and use the path /home/apps/Logiciels/ANSYS instead of /share/apps/ANSYS:
