Converge is an innovative computational fluid dynamics (CFD) software that eliminates the grid generation bottleneck from the simulation process through autonomous meshing. It accommodates complex moving geometries and features state-of-the-art physical models and a robust, fully coupled detailed chemistry solver so you can take on the hard CFD problems*.
Here is a quick step by step walkthrough to guide you through the different steps of how to run a Converge test case on Qarnot, so follow along!

Before starting a calculation with the Python SDK, a few steps are required:
Note: in addition to the Python SDK, Qarnot provides C# and Node.js SDKs and a Command Line.
This test case will show you how to launch a wind tunnel simulation on an airplane wing. The input files can be found in the following archive.
Once you have downloaded everything, your working directory should look like this:
wind_tunnel: contains case input files
run-converge.py: launchs the computation on Qarnot (code found below)
Launching the test case
Once everything is set up, use the following script to launch the computation on Qarnot. Be sure to copy your authentication token in the script (instead of
<<<MY_SECRET_TOKEN>>>) to be able to launch the task on Qarnot.
To launch this script, simply copy the following code in a Python script and execute
python3 run-converge.py & in your terminal.
At any given time, you can monitor the status of your task on Tasq.
You should now have an
output folder in your working directory on your computer and a
converge_out bucket in Tasq containing all output files.
Most notably, the directory
output/ contains the
.h5 files that can be visualized on tools like Paraview to have something like this
