General Description

Short Info

Platzhaltertext (diese gesamtseite ist noch zu schreiben, nur das format ist bereitgestellt).

Die verschiedenen Version erklären, evtl. in Tabelle: DIR, NDIR, Node Plane, NodeVec

Gehört NodeSpaceBound auch in diese Gruppe? Dann evtl. auch das source-File in den entsprechenden Unterordner schieben.

evtl ein bild zur erklärung

Parameters in the Input File

Compulsory Parameters
Parameter	Values, Default(*)	Description
MATERIAL	EL-MAT int	Linking to a material input block
INT_TYPE_HEXA	FULL, REDUCED	Control of integration type 20-noded elements are able to perform a uniform reduced integration (2x2x2 instead of 3x3x3) without hourglassing stabilisation
Optional Parameters
Parameter	Values, Default(*)	Description
EAS	int	Flag Enhances Assumed Strains (EAS) method Possible values are: 0* = EAS off 9 = full and locking free linear strains can be described (recommended for one axial bending) 15 = ellimination of parasitic bi-linear strains 24 = full and locking free bi-linear strains can be described (recommended for two axial bending) 30 = full tri-linear strains can be described
