Class PbTetrahedronMesh3D

  • All Implemented Interfaces:
    java.lang.Cloneable
    public class PbTetrahedronMesh3D
extends PbIndexedMesh3D
implements java.lang.Cloneable
    Defines a mesh of tetrahedrons. Class to define an indexed 3D mesh made up of tetrahedrons. This mesh is defined by a list of tetrahedrons. Each tetrahedron is defined by 4 indices of nodes.

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

    Each facet of a tetrahedron may have 2 references in the mesh, that is, one facet is common to 2 tetrahedrons. 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.
