active_learning_cfd

Active learning based regression for CFD cases

Requirements

This requires the following packages and their dependencies:

  • numpy
  • matplotlib
  • modAL
  • PyFoam

To run the examples, it is also needed:

  • sklearn

Installation

We recommend that the package be installed in development mode:

pip3 install -e .

Usage

Examples cases are provided in the example folder.

The test cases presented on the article are available on the cases folder:

  1. static_mixer
  2. orifice
  3. mixer
  4. mixer3D

Each case is composed by a folder with the OpenFOAM template and a runner python script for running the case and extracting outputs. The regression_batch scripts run a set of different strategies, with the possibility of repeating each one several times for statistics. The reference scripts generate reference results for estimation of interpolation error.
