Remarks

Class to define an indexed 3D mesh. Each cell of this type of mesh is a polyhedron with 4, 5, 6 or 8 nodes. Each polyhedron is defined by a list of node indices.

The nodes coordinates are defined by 3 arrays x_nod, y_nod, 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] = 4, the i-th cell is a tetrahedron, if cell_type[i] = 5 it is a pyramid, if cell_type[i] = 6 it is a prism, and if cell_type[i] = 8 it is an hexahedron. 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 facet of a cell may have 2 references in the mesh, that is, one facet is common to 2 cells. 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.
