nukewang is on a distinguished road
I am doing simulation of heat transfer from solid pebbles to flowing water. But the T-energy residual can not converge to 10^-3 while all other residuals is fine. I have tried using different timescales(for example, 0.03s for fluid and 5s for soid, automatic timescale for both, automatic timescale for fluid and 5s for solid), but it still fails. Anyone knows how to check what is wrong and how to fix it?

My model is pretty simple, I attached a picture of the GEO model here. Inlet boundary is used at the bottom and opening boundary is used at top. For the other four sides, symmetry boundary is used. I also put the converge resluts here.

Any help is highly apprieciated.
Best regards.
