Hi everyone,

I hope to get some advice on setting up a FAME combustion model in Converge. I found a reduced mechanism at https://creckmodeling.chem.polimi.it...ed-mechanisms/ and tried implementing it, but I'm encountering issues.

My simulations either don't run at all or produce incorrect results.

My setup:
Solver: Converge (SAGE for combustion modeling)
Turbulence Model: RANS
Simulation Time: Compression and Combustion phases only
Objectives: Evaluate Mean Pressure, Mean Temperature during combustion, Mass of Particulate Matter, and NOx emissions

I've successfully run similar simulations for conventional diesel with a different mechanism. Here's an image of my typical diesel setup (if helpful).

Has anyone used this specific FAME mechanism from https://creckmodeling.chem.polimi.it/ in Converge? If so, could you share any tips on setting up the simulation for accurate results?

Thanks in advance for any assistance!

Hey Carlos,


Please send the setup to "support@convergecfd.com", so we can take a better look at the mechanism and the case files.

Thanks,
Basu
