CFD Online Discussion Forums - develope a solver

Hi everyone
I want to develop a solver by adding the following Eq to simpleFoam solver:

http://latex.codecogs.com/gif.latex?...wn%20T%29/T%5D

http://latex.codecogs.com/gif.latex?%5Crho,c,k,D and S are constant.
V:velocity vector
T and L are scalars.

I've considered these assumptions:
m=fvc::grad(L)
n=fvc::grad(T)/T
and define m and n in createfields and finally write TEqn as bellow:

Code:

  fvScalarMatrix TEqn

 (

   rho*c*fvm::div(phi,T)

  -fvm::laplacian(k,T)

 );



 solve(TEqn == rho*c*T*(D*(m&n)+S*(n&n)));

  m=fvc::grad(V);

  n=fvc::grad(T)/T;

dimensions of variable and constants are listed below:
http://latex.codecogs.com/gif.latex?%5Crho [1 -3 0 0 0 0 0 ]
c [0 2 -2 -1 0 0 0 ]
D&S [0 2 -1 0 0 0 0]
k [1 1 -3 -1 0 0 0]
variable L is volume fraction and has no dimension.
variable T is temperature:[0 0 0 1 0 0 0]

I've made this new solver with wmake command successfully but when I run the case and want to complete the solver I confronted the following Fatal Error:

Code:

can anybody help?
