Multigrid methods are described for solving the pressure equation arising from a ®nite element discretization of the equations modelling the ¯ow of two immiscible and incompressible ¯uids in a heterogeneous porous medium. Comparisons are made between the performance of these methods and a preconditi

## Abstract Computation of a moving interface by the level‐set (LS) method typically requires reinitialization of LS function. An inaccurate execution of reinitialization results in incorrect free surface capturing and thus errors such as mass gain/loss so that an accurate and robust reinitializati
