Xfem manager record and associated records

This record creates corresponding xfem manager and specifies the number of its components, in terms of number of enrichment functions, enrichment items, and geometry items. The global shape functions are represented by individual enrichment functions. The enrichment items are abstractions of entities, which are included in the FE model using one or more global functions. Such entity may represent crack, material interface, slipping interface, etc. The particular records will follow immediately in input file. The general format is:

XfemManager	numberofenrichmentfunctions(in) #
	numberofenrichmentitems(in) #
	numberofgeometryitems(in) #

where numberofenrichmentfunctions represents number of enrichment functions and their associated records, numberofenrichmentitems represents number of enrichment items and corresponding records, and numberofgeometryitems represents number of geometry items, that are used to define the geometry of individual enrichment items.

The enrichment function records describe individual enrichment functions. The general format is following:

*EntType

(num#)(in)

The geometry item records describe individual geometries of enrichment items. The general format is following:

*EntType

(num#)(in)

The enrichment item records describe individual enrichment items. The general format is following:

*EntType	(num#)(in)
	(geometryitem#)(in)
	(enrichmentfunction#)(in)
