Problem for PDE creation

I'm using the The General Form PDE Interfaces module to create PDE for phase field equation solving. This module shows that I can input a Γ as an divergence item (▽· Γ ) and this causes a question: when I input M▽c as Γ ( ▽· (M▽c) ), will Comsol process this as M▽· (▽c) or ▽M·▽c+M▽· (▽c)? If it is the first, should I add a ▽M·▽c item as the source item?

COMSOL computes the divergence correctly; you do not need to add any term.
