Default divergence in AMG:enthalpy
Posts: n/a
Dear All,

I'm working on fixed bed gasifier, steady state. fuel inlet from the top, air from the bottom of combustor while the product gas leaves from the top also.

I used prePDF to define non-premixed. i model the solid fuel using group injection.

After some iteration, a message appeared" error: divergence in AMG solver: enthalpy". How to fix this problem and how does this actually happen?

I would like to hear any advice and suggestion from you,

Thank you

Regards, Ernie
