Flotherm- divergence
 
Hi,

I am running into a divergence issue here. I am modeling some channel flow and I start with just solving for the flow and it converges. However, when I model flow and heat transfer, all the variables show oscillatory behavior. I had checked my thermal BC and there is nothing wrong. Anyone know why does this behave this way ?? Based on my understanding, X,Y,Z-vel and Pressure should still converge in the flow and heat transfer model since the material properties are non-temperature dependent.
