How to set Zero normal pressure gradient in pervious boundary condition?

Please login with a confirmed email address before reporting spam

Hello,

I'm a student at Purdue, I benchmark a paper by modeling the cell with the properties and conditions in the paper.
By doing so, I met the final obstacle, set the zero normal pressure gradient with the pervious boundary condition.
I used the poroelastic physic and for darcy's law in the physics I need to set the boundary with zero normal pressure gradient.
I set the all term zero, ( pressure, elevation, and Rb) but it doesn't wok.

Please let me know how to set the normal pressure gradient is zero (dp/dn =0)

Thank you.

Q.
