hello Maher

In the case of 'fluent'

PCM zones Declares it as a fluid

then You must activate the operation of "phase changing"

(models----- solidification & melting)

In my opinion, if you are digging holes in the wall and placing the PCM

Greetings

Hi Maher,

you have to do it as phase change in fluid. you also could solve it as porous media (I think so)?

In Fluent by activating the melting and solidification model

I agree with Dr Mushtaq

Thank you Doctors

If I understood well in the case of fluent the first step is to activate the model VOF the second is to activate (solidification & melting) and finally all characteristics of PCM they will be modified in the rubrics (Materials) without touching (boundary condition) and more precisely the wall. This is valid in the case where for example the wall is composed of 5% PCM? And in the case where the PCM is put in the form of an internal layer separated from the concrete?

I will try to apply this on CFX if it is possible because I was worked before only with CFX
