Hi, Foamers.
I calculate one equation like B(scalar)*C(scalar)*D(vector)*E(scalar)*F(fvVector Field)
anyway, the type of the result must be fvVectorMatrix.
For the last term F is done with laplaceFilter, which has four kinds of operator as follows:
virtual tmp<volScalarField> operator() (const tmp<volScalarField>& ) const;
virtual tmp<volVectorField> operator() (const tmp<volVectorField>& ) const;
virtual tmp<volSymmTensorField> operator() (const tmp<volSymmTensorField>& ) const;
virtual tmp<volTensorField> operator() (const tmp<volTensorField>& ) const;
I use laplaceFilter to filter the velocity field "U".
D(vector) is the relative velocity between gas and liquid, or should it be a scalar?
