In heat transfer in solid model I need to set the domain temperature as a constant value(such as T=300K) In all the computing process. Now I can only set the boundary temperature.Thanks.

Hi
fixing the temperature of a domain to a fixed T value seems for me a bit strange, as approach, but basically it means you have to add a domain heat source field Q_domain(x,y,z,t) such that the temperature is set to your desired value.
If this Domain condition is not listed, it's rather straightforward to implement it via the weak constraints, by similarity with a constant T boundary condition (look at the equation view see options preferences ...)

Good luck
