On the porous jump boundary conditions

Now it is necessary to lay a thin layer of another porous medium on top of one, but the thin porous medium is too thin, about 30nm thick. Drawing a grid requires a lot of computer memory. Can we set a surface and assign it corresponding thickness, porosity, and permeability.

Hi, In Darcy's law there is a feature called "Thin Barrier", were you can implement what you described for interior boundaries. You can also add a Fracture feature (either on internal or external boundaries) and select Thin conducting barrier or Higly conductive fracture in the Fracture model list depending upon your modeling assumptions.

I've noticed that after the update of COMSOL 6.1, there is an added interface for coupled "thin barriers" (∇=∇n) in the multi-physics field of porous media multi-phase flow . Is there a corresponding interface for coupled thin membranes (∇=∇t)? Also, is it still not possible to couple porous media multi-phase flow with fracture flow?
