A tiny project to use ax-platform for multi-objective optimization on OpenFOAM cases

Multi Objective Optimization on OpenFOAM cases

If you're using this piece of software, please care enough to cite it in your publications

Relying on ax-platform to experiment around 0-code parameter variation and multi-objective optimization of OpenFOAM cases.

Objectives and features

• Parameter values are fetched through a YAML/JSON configuration file. Absolutely no code should be needed, add parameters to the YAML file and they should be picked up automatically
• The no-code thing is taken to the extreme, through a YAML config file, you can (need-to):
  • Specify the template case
  • Specify how the case is ran
  • Specify how/where parameters are substituted
  • Specify how your metrics are computed

How do I try this out?

Some examples, which range from simple and moderate levels of complexity, are provided as reference.

Strictly speaking, you don't need an OpenFOAM installation unless you are running a CFD case. You can always use your own code to evaluate the trials; but parameters must be passed through an OpenFOAM-like dictionary (See single-objective opt. example for inspiration.
