Abstract: The standard moment of fluid (MOF) method suffers “checkerboard” instability when applied to problems with surface tension effects. So the “continuous moment of fluid method” (CMOF) is introduced which eliminates the instability. Unfortunately, the interface reconstruction algorithm for the new CMOF method is 3 times as expensive as MOF reconstruction. We overcome the CMOF inefficiency issue by introducing machine learning, specifically we have found that decision tree works best for us. The specialty of MOF or CMOF is for sharp interface problems consisting of 3 or more diverse materials undergoing phase change. Some results are presented and compared with experiments. |
