Forced convection - horizontal flow against a plane sheet with a blunt edge

that's my first time I'm working with COMSOL MULTIPHYSICS and I'm trying to simulate a horizontal flow against a plane sheet with a blunt edge.
I use convective and conductive (cc) and Incompressible Navier Stokes (ns) mode with the following properties:
- forced - flow: 35m/s and -30°C
- plane - sheet: +4°C
When I try to solve the problem I always get the following error massage:
Failed to find a solution:
No convergence, even when using the minimum damping factor.
Returned solution has not converged.
Can someone give me a hint how to solve such a problem??? Maybe I just use the wrong models.....
