Dear All

I have compiled coupledmatrix and regioncoupling patches from openfoam 1.6ext in openfoam 2.1x successfully.
now Im trying t test the conjucatecavity tutorial for it. But there comes a problem

Reading/calculating face flux field phi

--> FOAM FATAL ERROR: 
Unknown patch field type regionCouple

Valid patchField types are :

13
(
processor
nonuniformTransformCyclic
processorCyclic
wedge
fixedValue
empty
cyclicAMI
cyclicSlip
calculated
regionCoupling
symmetryPlane
sliced
cyclic
)

    From function fvsPatchField<Type>::New

I dont know how can I solve it.
I appreciate any idea.

Hi Mahdi,

Quick answer - read the subsection "3.2.6 Linking new user-defined libraries to existing applications" on the OpenFOAM User Guide: http://www.openfoam.org/docs/user/co...plications.php

Best regards,

Hi Bruno

Thanks for the link.I have compiled them as a part of openfoam library not user library. just to explain my more my problem the problem is arising from this line of fvsPatchfieldNew.C when creating phi.

   typename patchConstructorTable::iterator cstrIter =
        patchConstructorTablePtr_->find(patchFieldType);

    if (cstrIter == patchConstructorTablePtr_->end())
    {
        FatalErrorIn
        (
            "fvsPatchField<Type>::New(const word&, const word&, const fvPatch&"
            ", const Field<Type>&)"
        )   << "Unknown patchField type "
            << patchFieldType << nl << nl
            << "Valid patchField types are :" << endl
            << patchConstructorTablePtr_->sortedToc()
            << exit(FatalError);
    }

Hi Mahdi,

I took a better look at the first post... shouldn't the name to be used be "regionCoupling" and not "regionCouple"?

Many thanks for your kind answer Bruno

Regioncouple is the name of regioncouplepolypatch and regioncouplefvpatch.
regiongcoupling is the name of fieldpatches.

regioncouple patches are based on couplefvpatch. as mentioned here by HRv for openfoam extended, http://www.cfd-online.com/Forums/openfoam-solving/57847-coupled-regions.html,
there is sth that is forcing that name of the patch and field should be the same. I checked the corresponding code in openfoam 1.6ext and openfoam 2.1x but i didnt understand where I can solve it.
just i should mention that regioncoupling in openfoam 1.6ext is working.

Hi Mahdi,

Mmm... I've taken a look into the source code of 1.6-ext and I found that the file "src/finiteVolume/fields/fvsPatchFields/constraint/regionCouple/regionCoupleFvsPatchField.H" has the following code:

public:

    //- Runtime type information
//     TypeName(regionCoupleFvPatch::typeName_());
    TypeName("regionCoupling");

On 1.5-dev it's still the exact same thing: http://sourceforge.net/p/openfoam-ex...tchField.H#l81

So, it's no wonder that "regionCouple" doesn't show up in the list And this probably means that Hrv hasn't fixed this yet, at least on these versions...

Best regards,
Bruno

Hi Burono,

Thanks for checking the codes. But if it is not fixed, how i can run the code in openfoam1.6ext?!

Hi Mahdi,

Probably there is a hack somewhere in 1.6-ext that forces the loading of the correct class?

Hi Bruno

I think that should be hard for me to do.
I check the patch type, there is a bool attach , if i make it false, it will pass the privious error but it will blows after the first iteration.

Hi Mahdi,

Have you tried changing:

TypeName("regionCoupling");

To:

TypeName("regionCouple");

in "src/finiteVolume/fields/fvsPatchFields/constraint/regionCouple/regionCoupleFvsPatchField.H", but only for your version in 2.1.x?

Best regards,
Bruno

Many thanks Burono,

Yes I have did it. but I got this
