k-omega internal flow simulation

Hello
I have a little convergence problem here.
I want to do a flow calculation with k-omega sst.
All settings are deafault.
The energy is still activated because the pipe runs in the component and the component is heated on one side. Now the convergence on this model is very poor.
I use uniform boundary layer with Growth Rate 1.05 and First Height 0.03. So that my Y-Plus value remains small.
What can I do to improve the convergence?
