<div>An improved algorithm for computing multimaterial/multi-phase flows is presented in which the multimaterial Moment-Of-Fluid (MOF) algorithm for multiphase flows, initially described by Li et al (2015), is enhanced addressing existing MOF difficulties in
computing solutions to problems in which surface tension forces are crucial for understanding salient flow mechanisms. The Continuous Moment of Fluid (CMOF) method is introduced in this article. The CMOF reconstruction method inherently removes the "checkerboard
instability" that persists when using the MOF method on surface tension driven multiphase/multimaterial flows. The new CMOF reconstruction algorithm is accelerated by coupling the CMOF method to the level set method and coupling the CMOF method to the Decision
Tree machine learning algorithm.<br>

<div class="ContentPasted0">Multiphase flow examples are shown in 2D, RZ, and 3D. Examples include two material and three material multiphase flows: bubble formation, phase change in a cryogenic fuel tank, freezing, and liquid lens dynamics.
