Two common methods for numerically calculating the evolution of the interface in a two phase fluid
through time are the level-set and the Arbitrary-Lagrangian-Eulerian moving-mesh methods. The levelset method is useful for spatial regions where topological change occurs, but is not very accurate; the ALE
moving-mesh method is more accurate, but it cannot readily accommodate topological changes. A
coupling boundary between these two methods is developed that allows a single simulation to use both
methods in different regions. In this way the best feature of both methods can be obtained. Results show
that the resulting hybrid model is as accurate as either method individually.
