== General Description ==

Coded and testing is in progress.

=== Element Type ===

* This element provides a geometrically nonlinear, isogeometric spatial cable.

=== Degrees of Freedom ===

The element uses the translatoric degrees of freedom (''Disp_X'', ''Disp_Y'', ''Disp_Z'') of the control points of the master element.

=== Parameter Description ===

|-
!Parameter
!Values, Default(*)
!Description
|-
!MAT
|EL-MAT ''int''
|Linking to a material input block
|-
!INT_TYPE_NURBS_BREP_CHORD
|FULL, USER
|Control of integration type. 
* FULL: p+1 Gauss points are used (p = polynomial degree of the NURBS patch) 
* USER: the optional Parameter GAUSS_U defines the number of Gauss points
|-
!CROSS SECTION 
|AREA = ''float''
|area of the cross section
|-
!PRESTRESS
|PRESTRESS = ''float''
|prestress of the cable element

=== Example of a Complete Input Block ===
<pre>
EL-PROP 1 : NURBS_BREP_CHORD  
  MAT= EL-MAT 1
  AREA = 1
  PRESTRESS = 4000
  INT_TYPE_NURBS_BREP_CHORD = USER or FULL
  GAUSS_U = 4
</pre>

== Element Loading ==

As the NURBS_BRep_Edge_Cord element is embedded into a master element, it can carry all loads which can be assigned to the master element:
