Hi everybody,
I'm studying Mechanical Engineering at Politecnico di Bari (Italy). I'm writing a thesis analyzing incompressible flow over an airfoil. (turbulence model: k-omega; flow velocity: 20 m/s; nu=10^-4 m^2/s; rho= 1 kg/m^3)

I made the mesh with Pointwise. I run it first with Fluent and it worked.

I tried to run the analysis in OpenFOAM so I adapted the "motorbike" tutorial to my case. But it doesn't work.

Create time

Create mesh for time = 0

Which is the problem? The smoothSolver? Boundary conditions? Mesh?
