I am modeling a simulation where in I have a heat source from outside which tracks the effect of PCM on heat storage and better evaporation of the other fluid.

Evaporation and Condensation model was added to one fluid whose Liquid Fraction is to be tracked. I want to add a Phase Change Material using Solidification/ Melting Modeling which will affect our dominant fluid. How do you I carry out both in ANSYS Fluent? As soon as I select the VOD modelling, and give PCM Cell Zone a fluid material input, it considers the PCM also to be part of VOF. I want it to be a separate fluid just undergoing phase change and no interaction with dominant fluid.
