Silvia CT New Member Silvia Calderón Join Date: Aug 2013 Location: México Posts: 6 Rep Power: 12	Dear all I'm simulating a tube with wall at uniform temperature, very simple I know. I got a Nusselt of 3.65..etc, close enough (almost 3.66, as in the literature), the problem is: as I refine the mesh Nu decreases and I don't know what is wrong, any ideas?? Saludos. __________________ Silvia Best Regards
