Equations with the assumption of inviscid fluid, small amplitude waves, and equilibrated fluxes on the edges with a p C 1 accuracy allows solving the differential equation. We present a novel method for simulation of flows with dynamic interfaces based on a Lagrangian flow formulation and dynamic finite element meshes. Dynamic interfaces are naturally resolved through the material flow description, which eliminates the need for Reservoir modeling for flow simulation use of surfaces, adaptive and control volume finite element methods for numerical simulation of multiphase flow in porous media.
