new compressibility model
 

Hi everyone,

I would like to create a new compressibility model (called nuevo_linear) for using with rasCavitatingFoam. I have used the linear model as a template, modifiying the files .C and .H. to define the compressibility as a function of gamma and pressure.

In the nuevo_linear.C file I have added the new equation, and the lines " const volScalarField& p " to take into account the pressure in the equation:

Foam::compressibilityModels::nuevo_linear::nuevo_l inear
(
const dictionary& compressibilityProperties,
const volScalarField& gamma,
const volScalarField& p
)

Furthermore, I have added a line to take into account also the pressure in the nuevo_linear.H file :

// Constructors

//- construct from components
nuevo_linear
(
const dictionary& compressibilityProperties,
const volScalarField& gamma,
const volScalarField& p
);

However, when I compile, I obtain the following error:

nuevo_linear.C: In constructor âFoam::compressibilityModels::nuevo_linear::nuevo_ linear(const Foam::dictionary&, const Foam::volScalarField&, const Foam::volScalarField&)â:
nuevo_linear.C:54: error: no matching function for call to âFoam::barotropicCompressibilityModel::barotropicC ompressibilityModel(const Foam::dictionary&, const Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>&, const Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>&)â

Could anyone help me to understand what is my mistake??

if your familiar wich c++, which is not my case, implementing new stuff should be easier.

in your case you got this is the first error you gotta debug. at line 54.

and go over .H and .C files to see which other files are involved

try checking the dependencies, classes and members at http://www.openfoam.org/docs/cpp/

hope it helps
sry can't be of more help
