Dear all
I am using reactingFoam for one of my flame simulations. But I dont know why it is not spitting out properties like density and viscosity as an output. The density should be a function of P and T from ideal gas law and viscosity as a function of temperature from Sutherland law (used in this version of the solver). Could anyone PLEASE explain the reason why it is not spitting out in the output and how can I tell the solver to spit it out. Your kind help is highly appreciated. Thanks |

Check your createFields.H file, and for density, there should be something like:
Code:
volScalarField rho ( IOobject ( "rho", runTime.timeName(), mesh, IOobject::AUTO_READ, IOobject::NO_WRITE ), thermo.rho() ); |

Thanks a lot Dominic for your prompt reply.
Anyone has any idea of the viscosity to spit out? Can I use the same procedure as Dominic mentioned to change in createFields.H?? |
