Solution will not converge?
 

Hi,

I'm trying to simulate a wind tunnel test. The Fluent model has a fluid domain of 460 x 460 x 1220 mm, & at the center is a wing 'projected span' = 200mm, 'center chord' = 81.82mm.

The educational version I'm using is limited to 512,000 cells. I've tried to use a fine mesh with 'inflation' layer on the wing. Slightly bigger mesh in a 'sphere of influence' around wing. Again a slightly bigger mesh for the rest of the 'fluid domain'.

I'm using a coupled 'Pressure/Velocity', 1st order model, but can not get convergence. What should I do to try and get it to converge?

Just incase, I've attached the files below:
