Hello!

I am simulating a flow field over a flat plate. The flat plat has thickness 5 mm, its bottom surface is heat flux b.c. and upper surface is coupled b.c. since it is shared to both fluid and solid zones. The 3D simulation geometry is a quarter of full domain, therefore I have two symmetry b.c.

The problem I found is that when energy model is used after isothermal simulation, the result of surface heat transfer coefficient (or temperature on surface) shows over-prediction in first raw of cells from symmetry b.c. (see link below). The other raws of cells are verified with some experiment data.

Can anyone help me to find the solution?
