Detailed Description

Set integration rule to boundary elements.

This rule is used to integrate the work of external forces on a face, i.e. \(f \cdot v\), where f is the traction vector and v is the test vector function. The current problem features a Neumann bc with a pre-defined constant pressure. Therefore, if the test field is represented by polynomials of order "p", then the rule for the exact integration is also p.

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