We describe multi-material (more than two materials) interface reconstruction methods for 3D mesh of generalized polyhedrons. Basic information used in interface reconstruction is volume fractions of each material in mixed cell containing several materials. All methods subdivide mixed cell into set of pure non-overlapping sub-cells each containing just one(More)
A novel adaptive mesh refinement (AMR) strategy based on the moment-of-fluid (MOF) method for volume-tracking of evolving interfaces is presented. Moment-offluid method is a new interface reconstruction and volume advection method using volume fractions as well as material centroids. The mesh refinement criterion is based on the deviation of the actual(More)
