Hexahedron

Create a solid or surface hexahedron bounded by bilinear faces.

Syntax

model.geom(<tag>).create(<ftag>,"Hexahedron");

model.geom(<tag>).feature(<ftag>).set(property,<value>);

model.geom(<tag>).feature(<ftag>).getType(property);

Description

Use model.geom(<tag>).create(<ftag>,"Hexahedron") to create a general hexahedron. The following properties are available:

Table 3-58: Valid Property/Value Pair

Property name	property Value	Default	Description
p	double[3][8]	{{0,0,1,1,0,0,1,1},  {0,1,1,0,0,1,1,0},  {0,0,0,0,1,1,1,1}}	Corner coordinates.
type	solid | surface	solid	Object type.
selresult	on | off	off	Create selections of all resulting objects.
selresultshow	all | obj | dom | bnd | edg | pnt | off	dom	Show selections, if selresult is on, of resulting objects in physics, materials, and so on, or in part instances. obj is not available in a component’s geometry. dom, bnd, and edg are not available in all features.
contributeto	String	none	Tag of cumulative selection to contribute to.

For a hexahedron approximately aligned to the coordinate planes, the points in p are ordered as follows:

•	The first four points and the last four points projected down to the (x, y)-plane defines two negatively oriented quadrangles (quadrilaterals).

•	The corresponding plane for the second quadrangle must lie above the plane of the first quadrant in the z direction.

•	Generally oriented hexahedra have the points of p ordered in a similar way, except for a rigid transformation of the defining point set.

For information about the selresult and contributeto properties, see Selections of Geometric Entities.

Example

The following command generates a solid hexahedron object:

Code for use with Java

Model model = ModelUtil.create("Model1");

GeomSequence g = model.geom().create("geom1",3);

g.create("h1","Hexahedron");

g.feature("h1").set("p",new double[][]

      {{0,0.0,1,1.0,0,0,1.0,1},

       {0,0.8,1,0.0,0,1,1.2,0},

       {0,0.1,0,0.2,1,1,2.0,1}});

g.run();

Code for use with MATLAB

model = ModelUtil.create('Model1');

g = model.geom.create('geom1',3);

g.create('h1','Hexahedron');

g.feature('h1').set('p',...

   [[0,0.0,1,1.0,0,0,1.0,1];...

   [0,0.8,1,0.0,0,1,1.2,0];...

   [0,0.1,0,0.2,1,1,2.0,1]]);

g.run;
