Class PbHexahedronMesh3D

  • All Implemented Interfaces:
    java.lang.Cloneable
    public class PbHexahedronMesh3D
extends PbIndexedMesh3D
implements java.lang.Cloneable
    Defines a mesh of hexahedrons. Class to define an indexed 3D mesh made up of hexahedrons. This mesh is defined by a list of hexahedrons. Each hexahedron is defined by 8 indices of nodes.

    The nodes coordinates are defined by 3 arrays x_nod, y_nod, z_nod of num_nodes floats. The hexahedrons are defined by the array hexahedron_index of num_hexahedrons*8 integers. hexahedron_index[(n*8)+p] is the p-th node index of the n-th hexahedron of the mesh (0 <= p <= 7). Each hexahedron must be numbered by repecting the following rule : the 4 first indices define a facet of the hexahedron and orient it towards the interior of the hexahedron.

    Each facet of a hexahedron may have 2 references in the mesh, that is, one facet is common to 2 hexahedrons. The facets which are referred to once in the mesh define the mesh skin.

    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.
