PINNs for solving multiphase poroelasticity relations

Link to the paper - PINN-Poroelasticity

If you are interested in physics informed neural networks (PINNs) and coupled single and multiphase flow in porous media, please check out our work below: 

- We find it challenging to solve coupled poroelasticity relations using PINNs (data-free).

- To resolve this issue, we propose a stable training strategy based on the sequential fixed-stress-split algorithm. 

- We also explore the role of adaptive weights in training such relations simultaneously and sequentially.
