The grids may move in some blocks, and they do not have to match at block interfaces. However, in the resulting linear equation systems, all blocks are implicitly coupled and the method is fully conservative. data too long for column passwordWitrynaThe second approach uses only a fixed mesh, and represents the interface implicitly with some additional field. For example, this is the approach used by the Volume Of Fluid (VOF ), the Phase-Field method [8,9] and the Level-Set method (LS ). These methods in general provide easier coupling formulations and smaller algebraic problems but with ... data too long for column result at row 1
