(For scaled arguments sw and so do not necessarily add to one.) - TODO: SatFuncGwseg.cpp and SatFuncStone2.cpp for oil-water systems. opm/core/fluid/SaturationPropsFromDeck.hpp - Struct to accomodate cell-wise scaling factors. - Two flags indicating scaling and method. - Methods for parameter initialisation and scaled relperm computation. opm/core/fluid/SaturationPropsFromDeck_impl.hpp - Initialize scaling options and relevant cell-wise scaling factors. - Relperm evaluation modified for possible end point scaling.
