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.
