I am doing a 2D wind simulation in an urban area for a small wind turbine. When I start the calculation it gives me this error!

Divergence detected in AMG solver: x-momentum -> Increasing relaxation sweeps!

Error: Divergence detected in AMG solver: x-momentum
Error Object: #f

Please help me!!!

Thanks,

Luca.
