A computational technique called ELAFINT has been developed to handle the existence of highly deformed moving and free boundaries. These boundaries or interfaces cut through an underlying cartesian grid, leading to irregularly shaped control volumes in the vicinity of the interface. A method to reassemble these control volumes to maintain flux conservation has been designed. The accuracy of the methods at each stage of the development have been assessed. Currently highly deformed, moving interfaces with phase change can be tracked in conjunction with an implicit pressure-based Navier-Stokes equation solver. This methodology can be applied to solve fluid flow problmes in complex geometries.
