Heat model in multiphase
 

Dear all, I try to sim. heat transfer of solid in liquid phase flow in straigth pipe. When i used multiphase option, there is no option of heat model/thermal...to set the temp. at boundary/inlet. that if difference from 1 phase option. Then i try to used Fluid dependece ...option and specify the value of Temp. of solid and liquid in fluid (isothermal option). But ofter simulation, both temp. of solid and liquid are the same value that I inputed it. Why there is no temp. change of both phase . Please help me suggestion. Thank you
