Hi ,

I was wondering if anyone knows how to generate a mixed ( Neumann + Dirichlet ) boundary condition in Darcy Law physics in COMSOL 5.0 ? ... We have boundary conditions like "hydraulic head" and "mass flux" and "pervious layer" but we don't have something general for both head and flux. Any idea ?

Thanks,
Mehrdad

Hello

May I know where did you get the Pervious BC option? Is it part of the CFD module or do you have to add additional modules?
