In this script we solve the same infinite plane strain problem as in
[example:official-platewithhole], but instead of using FCM to create the hole
we use a NURBS-based mapping. A detailed description of the testcase can be
found in Hughes et al., Isogeometric analysis: CAD, finite elements, NURBS, exact geometry and mesh refinement
, Computer Methods in Applied Mechanics
and Engineering, Elsevier, 2005, 194, 4135-4195.
