Divergence detected in AMG solver?
 
Hello Friends,

My simulation today give me an error message:"Divergence detected in AMG solver:x momentum Error object:()

I have no idea what it means and how to get around it.

I like to be helped by members of the forum.

With advanced thanks

If I were you, I'would search Fluent forum for previous similar questions. You will find several guidelines.

Dear Alammer and Zahid,

Thank you for the tips.

I have found out that the problem was rather with the Fluent server to which I am a client. Now I can run the same mesh to convergence.

Greetings
