Installation

Dependencies

• OpenFOAM-v2312
• python Pandas, matplotlib

Installation

   pinnfoam> ./Allwmake

Usage

In pinnfoam/run/unit_box_domain

    unit_box_domain > blockMesh && pinnFoamSetSphere && pinnFoam 

Visualization

Run

    unit_box_domain > paraview --state=visualize.pvsm 

To view training loss diagrams jupyter notebook and open pinnFoam-visualize-single-training.ipynb', then execute Re-run and Clear Data`.

Grid Search

A primitive Grid Search using python.subprocess is implemented in run/pinnFoam-grid-search.ipynb, just re-run this Jupyter notebook. Visualization of the Grid Search is done by run/pinnFoam-visualize.ipynb.
