Convergence becomes very slow after adding thin material model for CHT
 
Hi,

After I add thin material model for CHT, the solid T-energy convergence becomes extremely slow. Did anyone have a similar experience? How to solve this problem? Solid temp step scale factor doesn't work.

You're solving for two different timescales which are orders of magnitude apart.

What physical timescales are you using and how did you calculate them?
