General Description

Element Type

• This element provides the geometric description of a point on a NURBS patch
• used for coupling, supports and loads

Degrees of Freedom

The element uses the degrees of freedom of the corresponding NURBS patch(es).

Parameter Description

Compulsory Parameters
Parameter	Values, Default(*)	Description
BREP_TYPE	COUPLING_DISP COUPLING_ROT COUPLING_DISP_ROT NO_COUPLING SUPPORT SUPPORT_ROT CLAMPED_SUPPORT CONNECT_DISP	coupling of displacements coupling of rotations coupling of displacements and rotations no coupling blocking of the respective displacements blocking of the rotational degree of freedom, if existing (mainly for BEAM_3D_NURBS_KLRod) clamped, movable support pulling two points together (not yet tested)
BL_FACTOR_DISP	float	penalty factor for displacements. Youngs's modulus x 100 recommended
BL_FACTOR_ROT	float	penalty factor for rotations. Youngs's modulus x 100 recommended
Optional Parameters
Parameter	Values, Default(*)	Description
NITSCHE	USER, AUTO, NONE	not yet implemented

Example of a Complete Input Block

EL-PROP 1 : NURBS_BREP_POINT
  BL_FACTOR_DISP = 1e5
  BL_FACTOR_ROT = 1e5
  BREP_TYPE = COUPLING_DISP_ROT
