transient conjugate heat transfer problem
 
I try to simulate time-dependent temperature of solid domain,but i have no idea about it,if i use a small time period the flow can be converged but the heat transfer is very slow,then i have to run solver for thousands of time step,it's expensive.But if i set a bigger time period the flow will be unstable. So can anybody tell me how to solve this issue?I need your suggestion,thanks in advance.

Why transient? Do it steady state!
