Accessing Mesh Data

To get the number of mesh vertices, use

int model.mesh(<tag>).getNumVertex();

To get the coordinates of the mesh vertices, use

double[][] model.mesh(<tag>).getVertex();

which gives you a matrix where each column corresponds to a mesh vertex.

To get the element types in the mesh, use

String[] model.mesh(<tag>).getTypes();

The following table lists the possible types. See Element Numbering Conventions for an explanation of each type.

String	Element	dimension	Number of Nodes
vtx	Vertex element	0	1
edg	Edge element	1	2
tri	Triangular element	2	3
quad	Quadrilateral element	2	4
tet	Tetrahedral element	3	4
pyr	Pyramid element	3	5
prism	Prism element	3	6
hex	Hexahedral element	3	8

To get the number of elements of a specific type, use

int model.mesh(<tag>).getNumElem(type);

To get the elements for a specific type, use

int[][] model.mesh(<tag>).getElem(type);

which gives you a matrix where each column contains the mesh vertex indices of an element’s corners.

To get the geometric entity number for the elements of a specific type, use

int[] model.mesh(<tag>).getElemEntity(type);
