Hello,


I'm currently trying to find out how GriMech is used inside Openfoam to calculate combustion processes.
For this purpose, i debugged the foamRun.C for the SandiaD_LTS Tutorial. But I can't find any references or classes that links to the mechanism.

I would be glad if somebody could help me.

If you actually opened the tutorial and looked in Allrun you would find that the very first application is

runApplication chemkinToFoam \
               chemkin/grimech30.dat chemkin/thermo30.dat chemkin/transportProperties \
               constant/reactionsGRI constant/thermo.compressibleGasGRI

It's all there, plain as day. How did you miss it!?

I apologize if my initial question wasn't clear.
I'm working on understanding combustion models in openfoam. A essential part are the transport equations for each component.
To solve these equations, it's necessary to calculate the reaction rate on the (RHS).
For instance, in the SandiaD tutorial case, the Eddy Dissipation Concept is used to calculate the reaction rate, but this method also requires to calculate the mean density, kinematic viscosity, and other parameters.
As I understand it, the density and kinematic viscosity are computed based on the coefficients provided in the GRI-Mech table.
However, while debugging in OpenFOAM, it seems that the program never steps into the functions where these calculations should occur.

have a look at the thermophysicalProperties dict in constant

consult the Thermophysical models section of your user's guide


btw debugging is only debugging if the code is not working as intended. You are playing in the sandbox
