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
