Premixed combution -- divergence at the first iteration
I am trying to familiarizing with premixed combustion.
I tried to use a duct with map (it's a test geometry). I use adiabiatic model and k-eps turbulence. I get "Error: divergence detected in AMG solver: premixc" at the first iteration. Maybe I initialize bad? Do you have a tutorial about premixed combustion? I's like to see a working case to understand... |

(Divergence detected in AMG solver: premixc)
Hi
I am trying to use premixed combustion model for a problem that I have solved it without using species. I am getting error from the first time step. "Divergence detected in AMG solver" Divergence detected in AMG solver, primitive error at node 1" > decreasing coarsening group size" Divergence detected in AMG solver, primitive error at node 1" > increasing relaxation sweeps" Also afetr I tried again changing a few parameters such as W-Cycle, Max coarse relaxation and coarsed by, in the Solution Controls windowone or two parameters I got Divergence detected in AMG solver. Do you know how can I solve this problem ? Thank you very much for your help |
