implement a diffusion term in the source

I want to implement the diffusion of a scalar $\nabla$ $\bullet$ ( $\nabla$ $\Phi$ ) in the source term , my ideal is use another scalar in DEFINE_ADUST, then get the gradient of the scalar by C_UDSI_G in the DEFINE_SOURCE finally use NV_DOT(C_UDSI_G,A);
can that be possible? has anybody done it before ?
any suggestion is appreciate !
