Darcy's flow in multiscale porous media #46

Hi everyone.
It seems that classical PINN framework does not work for multiscale (heterogeneous) porous media. I have a Darcy’s 2D (xy cartesian coordinate, time independent) problem with permeability field as the input and pressure distribution as the output. Any idea? Here is a sample.
Tnx so much.
