[Inderjot]

Hi, I had posted this in another forum but did not get reply. May be I posted in wrong thread. I really need help with this one. I have been trying to simulate he problem since one and half month but no results. The problem is as following:

I am simulating a thin(zero thickness) rectangular winglet in the rectangular channel. I created geometry in Design modeler. Extruded the channel and then extrude-->add frozen a cuboid from bottom wall. I gave one side of this cuboid as the wall. The boundary conditions are: inlet-velocity, outlet-pressure, bottom wall - flux, winglet wall and wall shadow as no slip and heat flux zero, rest of the walls are adiabatic too and one symmetry wall condition. Initially i created inflation for bottom walls and winglet, the mesh quality was not good, i did not get convergence. i tried to simulate only by giving inflation at the bottom wall still no use.

Can someone guide me through this please. Also, for winglet wall and shadow in adiabatic condition the BC should be heat flux zero, or the coupled BC, which by the way was its default setting.
I am using k-epsilon and enhanced wall treatment method.
