Sir, now everything has cleared in my mind. I left the value of face permeability as default, i.e. 1e+10, thickness of the porous medium as 50 m and C2 value as "0". As for C2 value, I read through ANSYS manual that it could be assigned as "0" for laminar flow simulations just like you said bc it's actually for turbulent flows. Unfortunately, when I run the program it still doesn't respond, no solution. I keep getting the error segmentation fault "zero flow" at porous jumps.Please see the screenshot I shared.The video you shared earlier actually explains very well how one could derive the coefficients of a porous region. Could we apply the same procedure you did?(curve fitting in excel by referencing the values of VOLUME FRACTION of SOLID MATERIAL and DIMENSIONLESS PERMEABILITY BETA of GLASS WOOL) They are a bit strange for my case since our porous jump is actually a transition zone between marine sediments, imagine 3 layers(bodies) and these porous jumps behave like membrane which allow water liquid flow and passes through them.So, for that kind of a membrane can we talk about some properties to be useful to extract the coefficients by curve-fitting them in excel? If so, which values(I mean you derived coefficients from experimental pressure and velocity data and for laminar flow one can derive coefficients by volume fraction of solid material and dimensionless permeability beta of gw) and how ?

I hope I didn't confuse you.Sir I cannot express my graditute for your time and consideration. You literally helped me out to realize what I'm dealing with, what is it that I'm missing and at which points I'm doing things completely wrong. I thank you Sir, for your generosity to share your knowledge.

Cheers,
