Good morning Lorenzo,
per default, the formulation for the 2p model is pw-sn. That means your
primary variables are the water pressure and the non-wetting phase
saturation (in your case oil I assume). Therefore, Indices::swIdx does
not exists as it is not part of your primary variables.
Since you are considering a two-phase system, just set the oil
saturation by doing
*values[Indices::snIdx] = 1.0 - std::min(smax, smin + exp_value +
small_number);*
This is what you want I guess.
Best wishes,
Dennis

Good morning,
I'd like to ask how to impose an initial condition on the water
saturation and not on the oil saturation.
Actually, what I implemented is the following:
const auto pos = fvGeometry.subContVol[scvIdx].global;
double x_0 = 0.;
double smin = 0.2121;
double smax = 0.7856;
double exp_arg = (0.5 -
pow((pos[0]-x_0)/(2.+cos(3.*sqrt(std::abs(pos[1]-75.0)))), 2.) );
double exp_value = exp_arg >= -100 ? exp(exp_arg) : 0;
double small_number = 1e-6;
* values[Indices::snIdx] = std::min(smax, smin + exp_value +
small_number);*
but this last line, should be imposed on values[Indices::swIdx] but if
I write it I get an error, not declared variable.
Thank you,
Lorenzo
