Start-up question

[Mike Waters]

I am trying to write a kinetic equation roughly in the form:
\frac{\partial\phi}{\partial t}= \alpha\nabla^{2}\phi + \beta\nabla^{2}T  ,

Where both T and phi are cell variables. I'm not sure how to describe 
the Laplacian of T in the kinetic equation.


What happens if I use this:

TransientTerm() ==DiffusionTerm(alpha)  + (beta  *  
T.getFaceGrad()).getDivergence()   ?



Thanks,
