Hi all,

I am solving a species transport problem in a multi-phase flow and afer some iterations, i got this error: divergence detected in AMG solver: water-species-0

What could be the problem and how do i go about it.

Thank you

Deside,
have you tried to change Under relaxation factor for water (Species)? from 1 to 0.75 or may be 0.25? sometime it works..

regards
Chetan
