Thermal expansion mass balance.

Hi,

I am working on model which involves phase change. I can model that successfully, but I noticed mass is varying as the temperature varies. (makes sense as volume is constant but density varies with T)

I tried coupling with thermal expansion Multiphysics, but still mass is varying.

In both the cases, I used volume average to find the mass of the domain. I also tried defining intop function and defined mass variable. Still the same.

I also checked comsol tutorials, I noticed the same issue.

How to build a model without mass change?

Thank you
