A geometrical Volume-of-Fluid (VoF) method approximates the interface that separates immiscible fluids as a set of piece wise planar elements, associated with cells of the discretized solution domain that contain both fluids. Geometrical intersection operations are used both on the piecewise planar interface approximation, and the cells of the discretized domain in order to numerically approximate the evolution of the interface. The geometrical VoF method is widely used for two-phase flow simulations, because it stringently conserves mass, allows for accurate calculation on surface tension forces, and is straightforward to implement in parallel in terms of simple message exchanges across process boundaries. Current research is focusing on the extensions of the geometrical VoF method to unstructured domain discretization, and dimensionally un-split geometrical transport algorithms, as well as a more accurate geometrical interface approximation. The unstructured discretization of the solution domain, and the un-split transport algorithm negatively affect the serial and parallel efficiency of the method. Therefore, there is a need for modern HPC techniques to be applied on the method implementation in order to improve its serial and parallel efficiency.
