Hello Foamer!


I work with CFDEM but my question is purely OpenFOAM.
I have modified the Smagorinsky turbulence model to create a subgrid viscosity depending on the field voidfraction (Vgas/Vsolid). My problem is after the first timestep "0" I get the error message:

--> FOAM FATAL ERROR:

cannot find file "/home/carl/CFDEM/carl-PUBLIC-5.x/run/viscosityTest_BG/CFD/processorX/1.25e-06/voidfraction"

I believe this is because in this folder only the data at the writeInterval is saved. How do I retrieve the data at time 1.25e-6 and so on?

template<class BasicTurbulenceModel>
tmp<volScalarField> BatchelorGreen<BasicTurbulenceModel>::k
(
    const tmp<volScalarField>& voidfrac
) const
{

    volScalarField solidfrac(scalar(1)-voidfrac);

    volScalarField c1(a_*solidfrac+b_*sqr(solidfrac));

    return tmp<volScalarField>
    (
        new volScalarField
        (
            IOobject
            (
                IOobject::groupName("k", this->U_.group()),
                this->runTime_.timeName(),
                this->mesh_
            ),
            c1
        )
    );
}

template<class BasicTurbulenceModel>
void BatchelorGreen<BasicTurbulenceModel>::correctNut()
{
    new volScalarField
    (
    IOobject
    (
        "voidfraction",
        this->runTime_.timeName(),
        this->mesh_,
        IOobject::MUST_READ_IF_MODIFIED
    ),
    this->mesh_
     );

    volScalarField k(this->k(voidfraction_)); 

    this->nut_ = this->nu()*k;
    fv::options::New(this->mesh_).correct(this->nut_);

    BasicTurbulenceModel::correctNut();
}
