Hello foamers ,
I'm currently studying source code of coupledFvPatchField so i will use it in my future research extension for Discretizing the Laplace operator , we need gradientInternalCoeffs and gradientBoundaryCoeffs so we have gamma*surface area*( gradientBoundaryCoeffs + gradientInternalCoeffs*internal field ) My question is how the those coefficients are evaluated for couple boundary condition so that we get the following results as stated in source code template<class Type> tmp<Field<Type> > coupledFvPatchField<Type>::gradientInternalCoeffs( ) const { return -pTraits<Type>:ne*this->patch().deltaCoeffs(); } template<class Type> tmp<Field<Type> > coupledFvPatchField<Type>::gradientBoundaryCoeffs( ) const { return -this->gradientInternalCoeffs(); } |
