LES iteration window
 
When using the Large Eddy Simulation, I arrive at a different window. I then obtain the following error.

Error: Internal error at line 437 in file 'amgif.c'. divergence detected in AMG solver Error Object: ()

Whats the trick to the LES model and its iterations?

Does anyone have experience here?

Re: LES iteration window
 
Your iteration doesn't converge. Try to reduce the time step width or the underrelaxation faktors in order to get a stable solution process.
