2-phase, transient flow in porous media

Hi there,

I recently came across Nvidia Modulus and checked the user guide. However, I could not find any tutorials about two-phase flow e.g. capturing a liquid and an air phase for void and filling prediction. Is there an implementation that enables similar simulation to the interFOAM CFD solver?

Best Regards

Hello, Multi-phase flows are not supported yet in Modulus. Internally we have looked into this a bit but don’t have any definite plans for releasing anything yet. The primary issue is handling the changing boundary between the fluids. There is some work doing this with PINNs though here, [2006.05311] Deep learning of free boundary and Stefan problems.
