Hi,
I modeled a Finned Tube. For Meshing I had a problem that it solved here in this website. In Fluent, unexpectedly, the residual for the energy is beginning to Increase after 50 iterations. The other Residuals-Parameters reduce against it. The report shows that the temperature is not in the allowed limit, it is very high. What can be the problem?

Thank you. The situation seems to be OK. Residuals-parameter reduced continuously.
