hi,
i tried to drive a new boundary condition in heat transfer module, at the end when i tried to run wmake command , the error below showed up. can anyone help me?
thank You
`````````````````````````````````````````````````` `````````````````````````````````````````````````` ```````````````````````
convectiveHeatFluxFvPatchScalarField.C:109:64: error: invalid initialization of reference of type ‘const Foam::fvsPatchField<double>&’ from expression of type ‘const PatchFieldType {aka const Foam::fvPatchField<double>}’
patch().lookupPatchField<volScalarField, scalar>(TName_);

`````````````````````````````````````````````````` `````````````````````````````````````````````````` `````````````````````````
and this is my convectiveHeatFluxFvPatchScalarField.C file . i've attached it.
the error says problem is in line 109 !

Line 109 is:

    const fvsPatchField<scalar>& T =
        patch().lookupPatchField<volScalarField, scalar>(TName_);

I am the class you are trying to create. I am an fvPatchField. When you call patch(), I will give you my fvPatch. If you use my fvPatch to call lookupPatchField, it will return an fvPatchField. You are telling me that you want an fvsPatchField? With an 's' after the fv? That's a surface field, and is a totally different data structure. Us fvPatchFields don't play nice with fvsPatchFields. There are some functions that allow us to talk together, but they use interpolation, which introduces instabilities.

What is T supposed to be? Maybe try changing it to an fvPatchField.

yeah David. you are right. there was an addition 's' in the code .
T represent the temperature field .
