Dear Foamers,
I wanted to simulate the case that CH4 leakage in the air on OpenFOAM 9, but I didn't want to involve combustion and chemical reactions, so I entered "active off" in "combustionProperties" to try to turn off combustion, but the calculation still resulted in the combustion reaction. I would like to ask for your help. /*--------------------------------*- C++ -*----------------------------------*\ ========= | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox \\ / O peration | Website: https://openfoam.org \\ / A nd | Version: 9 \\/ M anipulation | \*---------------------------------------------------------------------------*/ FoamFile { format ascii; class dictionary; location "constant"; object combustionProperties; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // combustionModel infinitelyFastChemistry; active off; infinitelyFastChemistryCoeffs { semiImplicit no; C 5.0; } |

Thanks for your patience!
For the Sandia-D case, I have tried to turn the combustion off and it's work according to the post (How to switch off combustion and reaction in reactingFoam). Sandia-D case is based on reactingFoam, but my case is based on buoyantReactingFoam. Their difference is that the buoyantReactingFoam case does not have the file "chemistryProperties" in the "constant" folder. So I don't know how to turn off the chemical reaction. Because if I just turn off the combustion and reaction in the "combustionProperties" and "reaction" respective, it will still report an error. The error is as follows: --> FOAM FATAL ERROR: lookup of combustionProperties from objectRegistry region0 successful but it is not a combustionModel, it is a none From function const Type& Foam:bjectRegistry::lookupObject(const Foam::word&) const [with Type = Foam::combustionModels::singleStepCombustion] in file /home/prq/OpenFOAM/OpenFOAM-9/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 178. FOAM aborting |
