ICP = 32 as ICP = 31, except that the strength coefficients are directly provided as inputs, rather than being calculated from the parameters αgn \alpha_{gn}αgn and αnl \alpha_{nl}αnl. The capillary pressure functions are then
Pcgn=− Pcgn,0 [(S‾n)−1/m−1]1/n{P_{cgn}}\quad = \quad - \;{P_{cgn,0}}\;{[{({\overline S _n})^{ - 1/m}} - 1]^{1/n}}Pcgn=−Pcgn,0[(Sn)−1/m−1]1/n
Pcgl=− Pcnl,0 [(Sˉl)−1/m−1]1/n − Pcgn,0 [(Sˉn)−1/m−1]1/n{P_{cgl}}\quad = \quad - \;{P_{cnl,0}}\;{[{({\bar S_l})^{ - 1/m}} - 1]^{1/n}}\; - \;{P_{cgn,0}}\;{[{({\bar S_n})^{ - 1/m}} - 1]^{1/n}}Pcgl=−Pcnl,0[(Sˉl)−1/m−1]1/n−Pcgn,0[(Sˉn)−1/m−1]1/n
where SmS_mSm = CP(1); n = CP(2); Pcgn,0P_{cgn,0}Pcgn,0 = CP(3); Pcnl,0P_{cnl,0} Pcnl,0= CP(4).
