You can certainly write f.grad.dot(g.grad), but that will be fully explicit and will not converge very well.
It's best to look at the equation in its entirety. Where did this term come from? Oftentimes, terms like this arise from relations like \nabla\cdot(f\nabla g) \equiv \nabla f \cdot \nabla g + f \nabla^2 g It is likely that you can combine terms in a way that is more implicit.
