CFD Online Discussion Forums - Multiplication of source term with div(T) is causing error

Hi guys,
I implemented TEqn in interPhaseChangeFoam. Now I am implementing source terms .
For that I have to multiply my thermal conductivity(K) with div(T).

My code lookks like this

Code:

Foam::tmp<Foam::volScalarField> 

Foam::phaseChangeTwoPhaseMixtures::myPhaseChange::kappaGradT() const

{



const volScalarField limalpha1(min(max((alpha1()), scalar(0)), scalar(1)));

const volScalarField& T = alpha1().db().lookupObject<volScalarField>("T");



  return

    ( 

      (limalpha1*lambda1_+ (1-limalpha1)*lambda2_) * div(T)

    );





}

My phase change model compiled well and also the solver . But when I run the test case its giving the following error

Code:

  hari@hari:~/OpenFOAM/hari-8/run/suckingInterface_6$ interPhaseChangeFoam_5

  interPhaseChangeFoam_5: symbol lookup error: /home/hari/OpenFOAM/hari-8/platforms/linux64GccDPInt32Opt/lib/libphaseChangeTwoPhaseMixtures.so: undefined symbol: _ZN4Foam2fv9divSchemeIdE27IstreamConstructorTablePtr_E

Can anyone suggest me whats wrong in my code
