Detailed Description

Class EnrichmentFront: describes the edge or tip of an XFEM enrichment. The purpose is to add a different treatment of the front than the "interior" enrichments. We may, e.g.

Apply branch functions at a crack tip for the element containing the crack tip.
Apply branch functions on nodes within a certain radius from the crack tip.
Exclude nodes touched by the front.

The desired behavior is obtained by choosing a suitable EnrichmentFront.

MarkNodesAsFront: Intput: -ioNodeEnrMarker: A vector with the same size as the number of nodes in the mesh where the nodes corresponding to interior XFEM enrichments are marked with 1, other entries are zero.

Output: -ioNodeEnrMarker: Modifies the vector by marking tip nodes as 2, meaning that they should get special treatment. May also modify the set of nodes enriched by the interior enrichment.

Several enrichment fronts enrich all nodes in the tip element. This help function accomplishes that.
