Hello!
Kindly can someone let me know that capillary pressure is continuous at the interface when flow is moving from low to high porous domain. Based on the capillary pressure's equation it should be discontinuous due to different porosity and permeability values.


Moreover, what boundary condition should I used to model this domain, especially the interface. I looked one B.C named as Porous Medium Discontinuity in Comsol but according to its theory flow is flowing from high permeable to low permeable domain. But, in my case it is opposite.
Thanks!
