public class PbIndexedMesh2D
extends PbMesh2D
implements java.lang.Cloneable

Defines a surface mesh of polygons. Class to define an indexed 2D mesh. Each cell of this type of mesh is a polygon with any number of nodes. Each polygon cell is defined by a list of indices in an array of nodes.

The nodes coordinates are defined by 2 (or 3) arrays x_nod, y_nod (and z_nod) of num_nodes floats. The cells are defined by the array cell_type (size num_cells) and cell_index. cell_type[n] defines the number of nodes in the n-th cells: if cell_type[i] = 3, the i-th cell is a triangle, if cell_type[i] = 4, it is a quadrangle... cell_index is an array of S integers, where S = cell_type[0] + cell_type[1]

• ... + cell_type[num_nodes - 1]. cell_index contains the num_cells lists of node indices which define each cell topology.

Each edge of a cell may have 2 references in the mesh, that is, one edge is common to 2 cells. The edges which are referred to once in the mesh define the limits of the mesh.

The values on the mesh nodes are defined by the PbMesh.addValuesSet(set_index,val) method, where val argument is an array of num_nodes floats.

Copy constructor.

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

get2DNodes

public PbIndexedMesh2D.NodesInfo get2DNodes()

Gets the mesh nodes coordinates (only x,y coordinates) .

setElemOrientation

public void setElemOrientation(PbIndexedMesh2D.ElemOrientations cell_orient)

Changes orientation of cells during visualization of 2D surface mesh. The ordering of the indices of an cell defines the direction of its normal vector and so its orientation. When the mesh is visualized in 2D, the direction of the normal of an cell is either Z+ or Z-. If any cell of the mesh does not have the same orientation, it can change the representation because the lighting depends on the orientation.

setGeometry

public void setGeometry(int num_nodes,
                        float[] x_nod,
                        float[] y_nod,
                        int num_cells,
                        int[] cell_index,
                        int[] cell_type)
