How to implement reconCentral in Openfoam1812

hbulus · June 22, 2020, 05:10

I tried to implement a limitedscheme reconCentral from foam extend 4.0 (foam40/src/finiteVolume/interpolation/surfaceInterpolation/limitedScheme) to openFoam v1812. But when i tried to compile the code i get this error :

Code:

I know how to imply an own solver, but an utility scheme i dont know. Any help will be very helpful.

Thanks for every response !

read the error code:

reconCentral.C:97:15: error: âunallocLabelListâ does not name a type
const unallocLabelList& pOwner = p.faceCells();

obviously, openfoam v1812 doesn't recognize unallocLabelList.

replace it with labelUList&.

Thanks for your response, i fixed some of the wrong parts, thanks to you!
But now, i got the error at the below. Since i dont know c++, i cant figure out. Could you help me with this too ?

there is a ";"-sign missing after const for your first template function.
please check the code above.

Thanks for your quick response, i added ";" sign of course

What i was trying to say , Do you see anything that makes no sense in C++ because it is still not compiled. I attached the .C and .H files if you might check.

geth03 · June 24, 2020, 05:44

i can't really judge if everything is ok, bc openFOAM is a really large library and i don't know each class and function.

when i try to modify something in OF, i usually try to fix every error code output in the terminal. it can be really time consuming.
in your case, you try to implement something from OF extend to OF v1812. as you already posted earlier, there was a class in the extend version which was named differently in v1812. so it would be wise if you would follow each error output and fix everything step by step instead of looking at each code line.

why does it not compile? is there any error-message?
what is the terminal output?

Yeap you are right. Some classes have been changed, it is not easy to know every of them. Maybe Prof Jasak the only person who knows.

Here is what the terminal gave :

your .H-file lines 149-150:

Code:

virtual tmp<GeometricField<Type, fvsPatchField, surfaceMesh>>
interpolate(const GeometricField<Type, fvPatchField, volMesh>&) const;

your .C-file lines 34-42:

Code:

template<class Type>
Foam::tmp<Foam::reconCentral<Type>>
//Foam::tmp<Foam::GeometricField<Type, Foam::fvsPatchField, Foam::surfaceMesh>>
Foam::reconCentral<Type>::New

(
    const GeometricField<Type, fvPatchField, surfaceMesh>&,
    const GeometricField<Type, fvPatchField, volMesh>& vf
)

in your .C-file you define something different than you declare in your .H-file.

the correct substitution should be:

Code:

template<class Type>
Foam::tmp<Foam::GeometricField<Type, Foam::fvsPatchField, Foam::surfaceMesh> >
Foam::reconCentral<Type>::interpolate
(
    const GeometricField<Type, fvPatchField, volMesh>& vf
) const

there is a mismatch, you don't define in your .C-file what you declared in your .H-file. If you want to implement the function you declared in your .H-file, you need to define it properly and accordingly.

I fixed the .C code later, but i uploaded the wrong one here. The output that i gave in my previos post, was gotten in form of the code as you said. You can try though. Sorry for misleading

can you please upload your correct .H and .C files.

i checked also the original source code and don't really know what the problem is. the code looks fine to me.

Thanks for your all effort. I gave you repetition point as return .
I really stucked with this problem. Is there anyone who can help?

Thanks for every response!

ok, lets try one more time

your .C-File from line 34 onwards:

Code:

template<class Type>

Foam::reconCentral<Type>::interpolate
//Foam::tmp<Foam::reconCentral<Type>>
//Foam::reconCentral<Type>::New

    const GeometricField<Type, fvPatchField, volMesh>& vf
   // const tmp<surfaceScalarField>& tsf,
   // const tmp<surfaceScalarField>& pSf
)  const //adjust this 	 
{

}

Nope, it didn't work

Were you be succesful with this change ?

geth03 · July 3, 2020, 03:32

i just checked the code once more and saw that this part was missing

hbulus · November 25, 2020, 02:41

Is there any code developer for Foam Extend or OpenFoam to help this little but hard problem for me?

clapointe · November 25, 2020, 13:25

A long time ago I ported the limiter to Openfoam 7. I don't know how this compares to v1812, but it may be closer than foam-extend.

Thanks a lot, i can make some modification from your codes, then it compiled. I wmake in src/finiteVolume/interpolation/limitedSchemes as reconCentral file with required Make files. However, when i try to run with this fvSchemes, it says Unknown discretisation scheme reconCentral :
ddtSchemes
{
default steadyState;
}

gradSchemes
{
default cellLimited leastSquares 1.0;
}

divSchemes
{

div(phi,k) Gauss vanLeerDC;
div(phi,omega) Gauss vanLeerDC;
div(R) Gauss linear;
div((nuEff*dev(grad(U).T()))) Gauss linear;
}

laplacianSchemes
{
default none;
laplacian(nuEff,U) Gauss linear limited 0.5;
laplacian((1|A(U)),p) Gauss linear limited 0.5;
laplacian(DkEff,k) Gauss linear limited 0.5;
laplacian(DomegaEff,omega) Gauss linear limited 0.5;
laplacian(1,p) Gauss linear corrected;
}

interpolationSchemes
{
default reconCentral phi leastSquares;
interpolate(U) reconCentral phi leastSquares;
}

snGradSchemes
{
default limited 0.5;
}

fluxRequired
{
default no;
p ;
}

Do you have any idea why it gives this error ?

EDIT I solved the problem, you have to add libs("linreconCentral.so") at the bottom of controlDict file because i did not compile at top level of src.
