ernie Guest 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
