Hello, yes, sorry, so what I actually want to impose is that the normal derivative of saturation at the right boundary is = 0 and as I understand since, sw  and sn are related, it doesn't matter which saturation. Regards, Lorenzo On 01.02.2019 12:12, Timo Koch wrote: It’s unclear what

Hi Lorenzo, It’s unclear what you mean: dsn/n is not the flux of the non-wetting phase, dsn/n=0 only means the capillary-pressure-driven part of the flux is zero. Anyway, for the immiscible two-phase model (2p) model, if you want to set the (1) the non-wetting phase flux to zero: return zero

Good morning, but so, how can I impose the flux of the non-wetting phase (oil) to be constant, dsn/dn = 0, at the right boundary? Kind regards, Lorenzo On 31.01.2019 0:43, Flemisch, Bernd wrote: 1) It seems that you are setting no-flow for the saturation on the right boundary. I'm not
