Elements

You must be careful with the signification of the word “element”, when it is used with singular or plural form :

• The class “Element” is a basic class. The classes Vertex, Edge, Quad an Hexa inherit from the Element Class. This class is used to call common function like getName(), setName() ...
• The class “Elements” (plural) represents a set of Elements (vertices, edges, quads an hexaedras). This class is used to implements grids or result of ome complex operations (join, prism, ...)

Element

Set a name of an element:

elt.setName(name)

Get a name of an element:

elt.getName()

Print the name of an element:

elt.printName()

Dump an element:

elt.dump()

Elements

Remove a set of elements from a document:

doc.removeElements(elts)

Number of vertices in a set of elements:

nb_vertices = elts.countVertex()

Number of edges in a set of elements:

nb_edges = elts.countEdge()

Number of quads in a set of elements:

nb_quads = elts.countQuad()

Number of hexahedrons in a set of elements:

nb_hexas = elts.countHexa()

Get the vertex number i:

vertex_i = elts.getVertex(i)

Get the edge number i:

edge_i = elts.getEdge(i)

Get the quad number i:

quad_i = elts.getQuad(i)

Get the hexahedron number i:

hexa_i = elts.getHexa(i)

Cross Elements

CrossElements inherits Elements. So you have all Elements functions available to CrossElements, plus the following functions:

part argument specifies the block of the cross elements where to search the vertex, the edge, the quad or the hexa.
