thanks for your replay
my problem is I couldn't understand how rho is initialized with basicRhoThermo in chtMultiRegionFoam
In my case, rho is calculated with equation of state but when I look in the file thermophysicalProperties in the constant directory in the tutorial case I didn't find rho
so my question is How rho is set in chtMultiRegionFoam and how to change it?

different equation of state are described in userguide, however forexample if perfect gas is selected then rho is a function of p and T , so no need to enter for density.
