Hello everyone,
I want to implement a Scalar Transport equation with a source term. But in the source term, there is a gradient of the C term (as given in the picture in red). How to manage this kind of term? I can put (UnC) this term in the Sp format.But what kind of treatment I need to follow for the gradient term.

Note: We can't just put the term in Su term; we need to take it as Sp ...

If anyone can please help me, I got stuck for many days.
