Good Morning,
Any help would be great. I am attempting to analyze a fuel injector flow set in Star CCM+ 18.06.007. I ran the first 5K iterations. - Non reacting RANS 0-2K - Ignition 2K-3K - Reacting RANS 3K-5K Once the flow is steady at 5K I am supposed to change to Turbulence modeling and implicit time stepping. Herein is where I am receiving the error "Detected a non-finite value in AMG Residual" |

Try the first timesteps after the switching with a (much) larger dt.
