Where are correct () and update() functions defined ?
 
Hi Foamers,

I am focusing the codes of sonicTurbDyMEngineFoam these days.
Do you know where is the correct() function defined in below code ?
Code:

thermo.correct();
And where is update() function defined in below code ?
Code:

bool meshChanged = mesh.update();
I appreciate your help.
Thanks and best regards,
Sasan.

P.S. correct function declared as a pure virtual function in basicThermo class.

For the first question "thermo.correct();"
It depends on what thermo model you are using. Take hPsiThermo as an example.
It is define in
/src/thermophysicalModels/basic/psiThermo/hPsiThermo/hPsiThermo.C

For the second question. This is used dynamic meshing.It also depends on what dynamic meshing utility you are using. If you use dynamicRefineFvMesh
It is defined in
/src/dynamicFvMesh/dynamicRefineFvMesh/dynamicRefineFvMesh.C

Dear Haomin

Thank you very much.

Best regards
Sasan.

Hi Sasan,Haomin and other dears
what does correct() do on thermo type?
I can't find thermo.correct() in the library below:

It calculate other properties from pressure and h or e.

thermo.correct() is just a wrapper for thermo.calculate(). See the code below for an example.

This has been discussed here already some time ago, search the forum and you will find more information.


Code:

template<class BasicPsiThermo, class MixtureType>
void Foam::hePsiThermo<BasicPsiThermo, MixtureType>::correct()
{
    if (debug)
    {
        Info<< "entering hePsiThermo<BasicPsiThermo, MixtureType>::correct()"
            << endl;
    }

    // force the saving of the old-time values
    this->psi_.oldTime();

    calculate();

    if (debug)
    {
        Info<< "exiting hePsiThermo<BasicPsiThermo, MixtureType>::correct()"
            << endl;
    }
}
