Aerofoil - Error Divergence Detected
 

Hello there,

I am completing a college assignment on a NACA0012 aerofoil with the following details: Angle of Attack - 2degrees, Velocity Onset -2m/s and Chord length - 1m.

The assignment requires 200 iterations

I got the following Error: Divergence detected in AMG solver: pressure correction

I tried changing to flexible cycle under Multigrid settings. Same error.

I tried reducing the number of iterations.

New Error: Divergence detected in AMG solver: x-momentum

Please help me!!:confused:
