Default AMG for NITA
Posts: n/a

I am using PISO with NITA (6.2). I am trying to assess and control convergence and thus watching residuals from the AMG.

For my momentum and k-e eqns it is not reaching the residual tolerance I specify. It seems to ignore it completely regardless of which AMG cycle I select (F or flex).

Is it just reaching machine round-off? How do I know my solution is converged when I can't monitor any flow properties?

Please help if you can, J.
