Divergence detected in AMG solver: x-momentum
 
Hello everyone,

I designed a blade for a turbine and now I'm trying to analyze it in 3D by FLUENT. As the blade is rotating I need to use moving reference frame for the fluid and set the blade as moving wall with the angular speed of 0 rad/s right ?. when I try to run the case I get this error: 'Divergence detected in AMG solver: x-momentum' . I checked my boundary conditions they seem ok and I reduced the relaxation factor for momentum but still I get the same error. could you please help me with, I don't know if the problem is because I'm not defining the boundary conditions correctly or there's something wrong with my mesh or for something else.

thank you,

You might consider asking the question the Fluent forum.

This is for flow-3d.
