Hi, I'm an studen who is trying to simulate natural convection in an enclousure. My proble is all the time y have te same message error. Error: divergence detected in AMG solver: x-momentum Error Object: () For my simulation I used a 2d dpuble precision; segregated an K epsilon standard. If someone can help me, I don't know which the problem is. Thanks

Hi Jordi,

if the grid check has been ok, try to underrelax the momentum equations. By the way, which discretization scheme have you used for pressure?

Cheers,

MCB

Hi, Thanks. Yes I have checked the grid, it was ok. For the moment I used for presure discretization standard, there is a better option for do that. Really thanks.

Hi Jourdi,

you should use "Body Force Weighted" as discretization model for pressure.

Cheer,
