“…Nevertheless, the construction of geometric representations suitable to IGA, from CAD geometries, remains the major unsolved issue and IGA is indeed a very efficient strategy on "simple" geometries (i.e., on 2D or 2.5D geometries [10,4,27]) but not for general three dimensional problems. For 3D objects the conversion of a CAD geometry into a geometry on which isogeometric methods are defined (IGA-ready) is challenging and has many similarities with the conversion to a FE domain: its automation is far from being at the state of the art.…”

“…We introduce the concept of embedded surface in order to overcome the geometric challenges highlighted in the previous section. The idea comes from Bauer et al [54] who considered univariate embedded entities. More precisely, they embed a curve into a surface.…”
