A semi-implicit double-point Material Point Method for both free-surface flow and seepage in deformable porous media

A new semi-implicit, two-phase, double-point formulation of the Material Point Method (MPM) for soil–water interaction with seepage and free-surface flows under large deformation is presented in this paper. The approach advances the water phase implicitly while keeping the soil phase explicit, enabling stable, efficien...
