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 2.94E-12 and see if you now get 2.94E-12 m/s, no matter what your kappa value is. If this is the case, I suggest that you best ask the support.
