Hello,
I'm working on a 3D Darcy fluid flow model with hydraulic gradients in the x and the z. I have a lower permeability subdomain within another subdomain.
Unexpectedly, there is a small component of flow in the y-direction near the interior boundary of the subdomain, probably due to the difference in permeability. I’d like to set this zero in case it affects the thermal properties I’m considering. Is there a simple approach by editing the Darcy equation? Or another approach? I’ve tried deleting the py_y variable from the equation to no effect.
Basically (-kap_dl/eta_dl*py) needs to be set to zero for the duration of simulation.
Thanks!
