Hi everyone;
I am using ANSYS 16.0 FLUENT module to study natural convection phenomena inside the casing. But there is a problem in temperature distribution while examining results i.e. temperature close to heater is low and away from heater is high.

I have few questions beside this problem please adress them;
1.How to apply boussinesq approximation in fluent
2.How to draw nusselt number along the wall

This is the modeling in ansys;
Point close to heater (cube) has low temperature while point away from heater has high temperature,,

Please share the link of any guide or tutorial related to natural convection study in ansys fluent 16.0
