COMSOL giving me wrong Ks value!

Hi, I am using the Richards Equation interface and there is an equation relating kappa (permeability) to k (hydraulic conductivity) which is written in the documentation but I have calculated by hand...

Re: COMSOL giving me wrong Ks value!

Hi, I use my own PDE written Richard's equation, so cannot comment much. It seems like the 2.94E-4 is the default Ks input into the permeability model by COMSOL. Try changing that to let us say...

Re: COMSOL giving me wrong Ks value!

Hi Suresh, You're totally right, thanks! I changed the value for kappa and got the same k as always, so it seems it doesn't care what the equation is, it's just keeping its own default value. I can...
