2D FLOTRAN, flow passing airfoil

Hi everyone,

I'm trying to do a transient + turbulent analysis of a symmetry airfoil.

Normally, the boundary conditions are Vx on upstream and zero pressure on downstream. But now I need Velocity in Y direction.

Putting a component of velocity Vy on upstream gave me a divergent solution (on turbulent parameters) and I couldn't fix it with the relaxation factors (MIR).

I have a little knowledge about this relaxation. If anyone know about this, help me please. Also, the way to apply BC. If there're other ways, give me some idea please. I have been trying to properly simulate vortex shedding from the trailing edge.

Thanks
Thor
