Thank you so much for the help. I continued the simulation. But why did my contour display seems all are red. Is it reasonable? I made the same question in this thread Heat transfer result for pipe outlet (ansys.com)
Inlet temperature 573K and computed temperature around 571K. Pipe diameter is only 1.219meter and land is 10m diameter. I expect this should not became all red.
Another thing is does contour display also one of the basis of a good simulation. I came up converged model. Appreciate your help always. Thank you
