unsmoothed contour of temperature

chem engineer · November 23, 2015, 10:23

Hi everyone
I want to model floor heating in a room in 2dimension mode. The floor heating part is in the center of the floor. The ceiling and other parts of the floor except the heating part are insulated, and the walls are at the constant temperature. There is convection in the room and the flow is laminar. When I model it in fluent 6.3.26, the contours of temperature are unsmoothed, but it is expected to be smooth. What should I change in order to have smoothed contours for temperature. I should say that I have used 10^-9 for the residuals. I will be thankful if anyone can help me solve this problem.

Hi,
please post a picture of your contours, so to better understand what you mean by not smoothed contour.

Hi,

If contour smoothening is your only issue, you can try Graphics > Contours > Select your parameters. On the left specify Levels = 40.

I tried this way but unfortunately it did'nt work. there is also another problem. the resulting nusselt number have 30% deviation from the true nusslet number.
