【 摘 要 】

A moving system made up of multiple fluids (e.g. air and water) may be defined by an evolving interface with a changing topology. MOF uses a piecewise linear interface reconstruction to numerically model deforming boundaries. Given a volume fraction V and reference centroid x for a material in cell {Omega}, we seek to find an interface {Gamma} that exactly captures V and minimizes error in x. This differs from Volume of Fluid methods.
