bbbsolver is on a distinguished road
Hello all,
I am looking to model fluid leakiness from brain tumor vessels into tumor tissue space in openFoam. To do this, i would like to amend the continuity equation so that it has a pressure dependent source term.
I would like: divergence of velocity = (Leakiness rate constant)*(p_constant - p)

Where (Leakiness rate constant) is the spatially varying value (known) that we would like to load from a data file of some type. I imagine the data file would have 4 columns where the columns correspond to x, y, z space and the leakiness value.
p_constant is a constant, known value of pressure.
p is the interstitial fluid pressure in a porous media that we would like to solve for.
Does anyone know how to help me? I would very much appreciate a detailed outline of how i could do this. If you dont know do you have any resources that could help? Anything is appreciated
