The equation I need to discret

The equation I need to discretize is not

s*grad(I)=div(s*I)-I*div(s)

In order to build a solver for

In order to build a solver for combustion I need to discretize the radiative transfer equation.
The RTE contains the term:

where I is a scalar and s a vector.
My problem...
