Good Afternoon all!

I'm trying to edit a solver to include Saturation temperature.

I created the following:

    dimensionedScalar Tsat
    (
        "Tsat",
        dimensionSet(0, 0, 0, 1, 0),
        transportProperties.subDict("phase2").lookup("Tsat")
    );
    

    volScalarField Mlv
    (
        IOobject
        (
            "Mlv",
            runTime.timeName(),
            mesh,
            IOobject::NO_READ,
            IOobject::AUTO_WRITE
        ),
        alpha2 * rho2 * ( T2 - Tsat)/ Tsat 
    );

    );

the problem is, Mlv is being calculated as a single variable for the entire domain, instead of being calculated for every cell. (AS in the Mlv feels have a single value uniform for all the domain)

i then tried using this approach:

    dimensionedScalar Tsat
    (
        "Tsat",
        dimensionSet(0, 0, 0, 1, 0),
        transportProperties.subDict("phase2").lookup("Tsat")
    );
    
    volScalarField Tsati("Tsati", Tsat);

which i saw being used by the default solver to make what i want for rho. However this crashes the compiler (which only says: make: *** [Make/linux64GccDPOpt/catarina.o] Error 1 )

I've removed the Mlv part of the code and the 2 lines before still crash by themselves. I've also replaced Tsat in " volScalarField Tsati("Tsati", Tsat);" by some other variable, e.g.: rho, and the code is compiled.

How does one add a VolScalarField based on a single constat?

Best Regards

ok, never mind.....

I forgot to add code to calculate these variables in the runtime loop....

Anyway, my question for the second bit of code still stands... why doesn't it work?

Best Regards

Greetings Pedro and welcome to the forum!

The last line doesn't tell the whole story . Please provide the complete terminal output, including the command you've used to do the compilation.

Best regards,

hi bruno

thanks for the reply. I ran the compiler so many times (wclean; wmake) today i failed to notice the text changed when there was an error

the error itself is

/home/pupo/OpenFOAM/OpenFOAM-2.1.1/src/OpenFOAM/lnInclude/GeometricField.C:209:1: note: candidate expects 4 arguments, 2 provided

anyway, i apparently don't need to create a volscalarfield for a static variable, as soon as i added the field i want to calculate into the runtime loop everything starting to work as expected....

Thank you for your time, if you want to clear the forum out of a useless thread... please do :/
