Detailed Description

Set integration rule to volume elements.

This rule is used to integrate \(\nabla v \cdot \nabla u\), thus if approximation field and testing field are polynomial order "p", then rule for exact integration is 2*(p-1).

Integration rule is order of polynomial which is calculated exactly. Finite element selects integration method based on return of this function.
