Class PbQuadrangleMesh2D

  • All Implemented Interfaces:
    java.lang.Cloneable
    public class PbQuadrangleMesh2D
extends PbIndexedMesh2D
implements java.lang.Cloneable
    Defines a surface mesh of quadrangles. Class to define an indexed 2D mesh made up of quadrangles cells. This mesh is defined by a list of quadrangles. Each quadrangles is defined by 4 indices of nodes.

    The nodes coordinates are defined by 2 (or 3) arrays x_nod, y_nod, (and z_nod) of num_nodes floats. The quadrangles are defined by the array quadrangle_index of num_quadrangles*4 integers. quadrangle_index[(n*4)+p] is the p-th node index of the n-th quadrangle of the mesh (0 <= p <= 4). Each quadrangle must be numbered by repecting the following rule : the edge linking the first and the second index must not be a diagonal of the quadrangle.

    Each edge of a quadrangle may have 2 references in the mesh, that is, one edge is common to 2 quadrangles. 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.
