Ansys Fluent on Qarnot Cloud - documentation

December 8, 2022 - Documentation, Numerical simulation


Ansys Fluent is a computational fluid dynamics (CFD) solver. It is widely used for industrial research and development and academic simulations.


This software is proprietary, a license is necessary in order to use it. If you want to test this payload on a real use-case, please get in touch with our team: qlab@qarnot.com.


Here is the current available version on Qarnot:

Release yearVersion
20222022 R1

If you are interested in another version, please send us an email qlab@qarnot.com.


Before launching a computation task, please ensure that the following prerequisites have been met:

Launching a use-case

Here is an example of how to run an Ansys-Fluent use-case on the platform. It assumes that:

  • you have access to a license,
  • your use-case includes data and a .jou file in a use-case folder in your working directory.


To launch the computation on Qarnot, copy the following code in a Python script in your working directory. Be sure you have copied your authentication token in the script (instead of <<<MY_SECRET_TOKEN>>>) and execute python3 ansys-fluent_mpi-test.py.

Launching a MPI test

Ansys-Fluent mpitest can run without license. To start a MPI test on Qarnot, copy the following code in a Python script. Be sure you have copied your authentication token in the script (instead of <<<MY_SECRET_TOKEN>>>) to be able to launch the task on Qarnot.


To run this script, open a terminal in your working directory and execute python3 ansys-fluent_mpi-test.py. It will launch the MPI test on Qarnot.


At any given time, you can monitor the status of your task on Tasq.
