Active learning symbolic regression, CFD + AI = Wow

Installation

You can install using pip once you clone this repo:

pip install alcfd@git+https://github.com/ur-whitelab/alcfd.git

Pre-requisites

  • ANSYS license to run CFD simulations.
  • jupyter to run example notebooks

SISSO installation and usage

SISSO is written in FORTRAN and needs to be compiled. You can find instructions on installing SISSO here.

For this project, the src/SISSO.f90 in their source code was changed. A patch file is provided in the Patches/ directory. Note: This patch is hard coded for the features that we used for our CFD systems. Users should change this depending on their system.

Usage

Refer to jupyter notebooks provided in the examples/ directory for example usage of CFD and Active Learning (AL) methods. Note that current working example models are compatible with ANSYSWB >= v2020R2.

To run SISSO on train.dat file using SISSO.in (both generated during AL), use this command:

mpirun -n 1 SISSO
