Hi i have model and it always error after first timestep 

Divergence detected in AMG solver: x-momentum

Divergence detected in AMG solver: y-momentum

Divergence detected in AMG solver: z-momentum

Divergence detected in AMG solver: pressure correction

Divergence detected in AMG solver: enthalpy

Error at host: floating point exception

Hello, 

if this error occurs at the very first time step, it would suggest that there is something wrong with your setup.

Can you tell us more about your model? Also, how is your mesh quality?

[Agung Limowa]

I think it because the setup issue, my model is a large 3d model with around 13 m cell and it has minimun orthogonal 0.03 and aspect ratio around 90. But i couldn't tell whats wrong with the setip

[Federico Alzamora Previtali]

Best practice recommends minimum orthogonal quality of 0.1, so I would suggest reviewing your mesh first.
