P_from_W_steady() void pism::hydrology::Distributed::P_from_W_steady ( const array::Scalar &  W, const array::Scalar &  P_overburden, const array::Scalar &  sliding_speed, array::Scalar &  result  ) protected Compute functional relationship P(W) which applies only in steady state. In steady state in this model, water pressure is determined by a balance of cavitation (opening) caused by sliding and creep closure. This will be used in initialization when P is otherwise unknown, and in verification and/or reporting. It is not used during time-dependent model runs. To be more complete, $P = P(W,P_o,|v_b|)$.
