Specify cell zone conditions for simulation of PCM

      There are many spherical PCMs (fuel cells) inside a water container I have created a fluid domain in order to simulate the flow of water in between the spaces around spherical pcm solids. I am using solidification/melting model.


      Can anyone help me define cell zone conditions and I also need to define PCM  for solid balls. After separating fluid domain(boolean-subtract), I have only fluid domain left.So, How should I specify material for PCM balls.


      PCM- Phase change Material


      Thanks in Advance.

      This looks to follow from this  https://studentcommunity.ansys.com/thread/how-to-select-and-specify-material-for-voids-after-boolean-subtract-operation/  where Peter told you that you need to subtract and retain the PCM balls from the flow region. 


      If you label these then you can separate the two zones with walls (if the PCM is retained in a shell) or to patch phases if they aren't.

      Thanks for the reply


      Yes, I did that, separated both PCM balls and fluid region and ran calculation in solidification/melting model.


      I ended up with following errors, How should I correct those. Pls click the below link.

       OK. I'll lock this thread and we can move to that one.
