inner product of two vectors in OpenFoamHi,
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)) |

yes, it depends on the operator between two! vector , if it is inner product, then
it would be fvc::grad(epsilon) & fvc::grad(epsilon) |
