Nicholas_Langbein New Member Nicholas Langbein Join Date: Nov 2024 Posts: 14 Rep Power: 2	Hello, I want to add a convection and diffusion term (strain rate dependent) to volume fraction equation to advect a particular phase in certain direction.. In the source code of VoF alphaEqn.H i tried adding a convection and diffusion flux ... but even with MULES alpha values blows up crazy. Is there a standard procedure or reference on how to add terms to alphaEqn.H (i cant use alphaSource because my terms are strainrate dependent) Should or how can i make it Implicit
