Multi-material interface reconstruction from the moment data

The purpose of the Moment-of-Fluid (MoF) technique is reconstruction of the mixed-cell material interfaces from the moment data: the volumes and centroids of materials. The governing principle of the MoF interface reconstruction is the minimization of the rst moment defect, subject to preservation of all material volumes. In the case of two materials this principle allows to nd the direction of the interface normal, and in the case of multiple materials this principle helps to determine the order, in which the materials should be separated. Compared to the competitors, the Volume-of-Fluid (VoF) interface reconstruction techniques, MoF algorithm shows higher accuracy, allows uniform processing of internal and boundary cells, and is truly robust in treating multi-material mixed-cells.
