non-conformal mesh
 

I am working in a natural convection problem. I have a very complicate geometry, that I have meshed using non-conformal mesh. But displaying contours I have got some discontinuitys in temperature contours, in the boundaries of different volumes. How can I resolve this problems? I have tried to smoothing the transition between the different volumes.

Thank youª

Re: boundary conditions in natural ventilation
 

I am working with fluent in natural ventilation problem, with Boussinesq aproximation. I have a heat source, and I want to get solution without definning inlet and outlet boundary conditions. I think taht the heat source must to force the air flow within the domain. Is it possible to simulate with fluent? How? I do not want to define velocity or pressure at the inlet, because I think this seting will have a decisive influence in the flow field.
