Dear OpenFOAM users.

I am using OpenFOam-1.5 I wanted to solve the transport equation for temperature variance for my research purpose. I have added Temperature equation and Trms equation in the simpleFoam code for the same purpose.( I have replaced buoyantSimpleRadiation code with SimpleFOam code since my original simpleFoam code is running with some other modifications in energy equation)

My TEqn.H file reads as

alphaEff = alpha + turbulence->nut()/Prt;

tmp<fvscalarmatrix>TEqn
(
fvm::div(phi, T)
- fvm::laplacian(alphaEff, T)
);
TEqn().relax();
eqnResidual() = solve(TEqn()).intialResidual();
maxResidual = max(eqnResidual, maxResidual);


My TrmsEqn.H file reads as

alphavariance = alpha + (0.13*(turbulence->k()*turbulence->k()/turbulence->epsilon()));

tmp<fvscalarmatrix>
(
fvm::div(phi, Trms)
-fvm::laplacian(alphavariance, Trms)
+fvm::Sp(fvc::div(alphaEff, T), Trms)
+0.134*(turbulence->epsilon()/turbulence->k())*Trms
);
TrmsEqn().relax();
eqnResidual = solve(TrmsEqn()).initialResidual();
maxResidual = max(eqnResidual, maxResidual);

On compilation i get following error

Any ideas on what the error actually means????
I know there is some mistake in the way in which the source term of Trms equation is written but i am not able to find out what and exactly how that term should be written. Can anyone please help me?????????
