Iterating
 

Hi, I keep getting this error message when trying to begin iterations in Fluent. What does it mean please?

Error: divergence detected in AMG solver: x-momentum Error Object: ()

iter time/iter

Re: Iterating
 

check for your boundary conditions and scaling

Hey Naghman

AMG is the Algebraic MultiGrid solver. (basically the solver)

Your solution is not converging. Start with lowering the under-relaxation factors in the (Solve-->controls-->solution) panel. Also, make sure that density is not assigned as a "constant" if your model involves temperature gradients or compressible flow.

Good Luck!
