sam1364 Member pooyan Join Date: Nov 2011 Posts: 62 Rep Power: 15	Hi, I have a mathematical operation in the form of (depsilon/dxi*depsilon/dxi) in which d(epsilon)/dxi is the gradient of epsilon. So, I have a inner product of two gradient vectors?! Can I show this inner product as the follwoing way?! fvc(grad(epsilon))&fvc(grad(epsilon))
