This is a partly premixed combustion model.When I iterate, the fluent shows liks this: Updating solution at time level N... done. iter continuity x-velocity y-velocity k epsilon fmean fvar premixc time/iter
reversed flow in 49 faces on pressure-outlet 4. Error: divergence detected in AMG solver: x-momentum Error Object: () Interrupting... Done. I want to know what the problem is.Thank you very much! |

somewhere some variable is divided by 0. U should avoid this my decresing the residual.

I can give some ideas first note at which iteration u are getting such a problem then time u iteration just beofre that iterations where u get this problem and then plot the contours of all the solved variables and see where the soleution is reaching negative or 0.
