Hello Ait,
I don't know if I understand your question right but Pe and Lambda are
soil parameters (or more preciously, empiric parameters that determine
the shape of your Brooks Corey pc-saturation curve) which you can set in
your spatialparams.hh file.
To my knowledge, these parameters do net depend on the actual phase
pressures.
Best regards
Kilian

*Hello,
when using the laws of capillary pressure defined in Brook Corey, i.e.
*
*$$P_c(S)= Pe * (S)^(-1/\lambda)$$
*
*the choice of parameters Pe and \lambda in decoupled_tutorialproblem,
is Pe= 500 and \lambda = 2.
*
*My question is: the choice of Pe and \lambda depends on the pressures
used in the .hh file? If yes, how this choice is made?
*
*Kind regards.
