[Nek5000-users] wgradm1

Hi Neks,

I had a quick clarification question about the subroutine wgradm1.  The comments suggest it is a weak gradient, but the formulation itself looks like it is computing a strong gradient (and multiplying by mass), i.e.,

  grad(u) = W*G*D*u

(W being the weights, G being the appropriate metrics, and D begin the normal derivative operator).  Is this correct, or am I missing something?

Thanks,

Josh
