Hi there,

sorry im relativly new in openFOAM and i want to solve the following equation:

div ( -k grad (p) ) = U

it is a equation for groundwater flow in the subsurface, k is the permeability(vector field), p the pressure and U the flow velocity.

i tried to write a new solver but it didn't manage it. I can someone give me some hints, how to build the equation in the solver ?

or maybe i have overseen a standart solver, that can handle the problem.

thanks in advance

greetings
andreas
