use a boundary condition like internalField for just one volScalarField

Hi dear foamer.
I wanna remove a boundary for just a field. for example I have 5 boundary condition and for energy Eq I want to use just 4 boundary condition and another Bc operate like internal face. do you have Idea about that? I change internalCoeffs and boundaryCoeffs but my matrix component changed.

HTML Code:

     TEqn.internalCoeffs().set(0,new Field<scalar>(0,pTraits<scalar>::zero));    TEqn.boundaryCoeffs().set(0,new Field<scalar>(0,pTraits<scalar>::zero));

can I create two object of fvmesh class which read different boundary directory and remove this BC in one of the boundary file?

Does anyone have an idea?
