how to avoid strange keywords

Hi All,
I coded function

Code:

tmp<volVectorField> fun()

{

    return tmp<volVectorField> 

             (

                  fvc::div(rho1/rho2*B*B*G*G)

             );

};

and when I run the solver I got this message like

Code:

keyword div((((rho1|rho2)*B*B*G*G) is undefined in fvSchemes

how to avoid this?

Try following in Solver:

Code:

fvc::div(rho1/rho2*B*B*G*G,"weirdDivergenceTerm")

and in fvSchemes:

Code:

weirdDivergenceTerm Gauss upwind; //as an example
