I am modelling the (laminar) flow through filter media. It works fine with the porous zone boundary condition, but I have convergence problems with the porous jump b. c.

I. e. the solution does not converge for pressure drops higher than a few Pascal. Has anyone an idea what could be the cause for this?

As I know, the Porous Jump condition is suitable to 1D case, and Porous Zone is suitable for other cases
