Dear All Foamers,

I am bit new to openfoam programming and have been working on writing a solver based on existing solver. But I am getting following error. Can you tell me what is the problem. Actually same piece of code works very well in other solvers but in my code, while compiling I get error's mentioned below.

CODE:

surfaceScalarField phiUf("phiUf",(fvc::interpolate(phiU,"phiU")) & mesh.Sf());

//- phiH

surfaceScalarField phiH("phiH", (fsf*Kf*(ROL-ROV)*hlg*g/nuv) & mesh.Sf());

ERROR'S:

updateSbProperties.H:95:51: error: no match for ‘operator&’ in ‘Foam::fvc::interpolate(const Foam::GeometricField<Type, Foam::fvPatchField, Foam::volMesh>&, const Foam::word&) [with Type = double]((* & Foam::word(((const char*)"phiU"), 1))) & mesh.Foam::fvMesh::Sf()’

You can see that this code for getting phi is standard and is giving no error in original solver but I dont understand why I am getting these mismatch error's for operator&.

Please tell me how to sort it out.

Thanks & Regards,

What OF version are you using?

I'm not an expert, but judging from the error and judging from a search on "fvc::interpolate" (in OF-2.3.x), I can't help but notice that your interpolate has two arguments, whereas the search results always (I went through the first 40 results) have one argument.

So change

surfaceScalarField phiUf("phiUf",(fvc::interpolate(phiU,"phiU")) & mesh.Sf());

to

surfaceScalarField phiUf("phiUf",(fvc::interpolate(phiU)) & mesh.Sf());

and see if that works.

.

I tried your suggestion but same errors came again. I think it has some thing to do with the datatype of return value of fvc::interpolate(phiU). Thanks for your reply. ANd mine is version 2.3.0-OF.
Please somebody suggest me what I have to do to remove this error.

Greetings to all!

@Bharat Bhushan Sharma: The problem is that you're trying to interpolate a surface scalar field, which isn't a standard interpolation in OpenFOAM. As detailed here: https://github.com/wyldckat/reconstr...te-fields/wiki

More specifically, it will interpolate the fields that exist in the cell centres onto the face centres. This operation is only done for the following field interpolations:

• Interpolate volScalarField to surfaceScalarField.
• Interpolate volVectorField to surfaceVectorField.
