General Description

This element is coded but not extensively tested.

Element Type

  • This element provides an geometrically nonlinear, isogeometric solid element.
  • Mass computation is implemented (assumption of constant density in element).

Degrees of Freedom

The elements uses three translatoric degrees of freedom (Disp_X, Disp_Y, Disp_Z) at each control point.

Parameter Description

Compulsory Parameters
Parameter Values, Default(*) Description
MAT EL-MAT int Linking to a material input block
INT_TYPE_SOLID_NURBS FULL, USER Control of integration type. If USER, the optional Parameters GAUSS_U, GAUSS_V and GAUSS_W has to be defined
Optional Parameters
Parameter Values, Default(*) Description
GAUSS_U
GAUSS_V
GAUSS_W 		GAUSS_U = int
GAUSS_V = int
GAUSS_W = int 		Number of Gauss point per element in u-, v- resp. w-direction. Must only to be defined when INT_TYPE_SOLID_NURBS = USER

Example of a Complete Input Block 

EL-PROP 1 : SOLID_NURBS 
  MAT= EL-MAT 1
  INT_TYPE_SOLID_NURBS = USER !or FULL
  GAUSS_U = 4
  GAUSS_V = 4
  GAUSS_W = 4

Element Loading

The SOLID_NURBS element is able to carry the following loads:

  • dead load

Benchmarks

The main benchmark file in the Carat++-repository is

  • '../examples/benchmark_examples/isogeometric/11_isogeometric_solid/cbm_isogeometric_solid.txt'.
