Detailed Description

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.

Member Function Documentation

◆ getCell()

virtual const PbCell * PbHexahedronMesh3D::getCell ( int cell_index ) const

virtual

Gets the cell which index is cell_index.

Returns NULL if the cell does not exist, otherwise returns always a PbHexahedronCell object. Attention! this method returns always the same adress of an internal private cell. This private cell is updated each time getCell is called.

Reimplemented from PbIndexedMesh3D.

◆ getGeometry() [1/2]

Gets the current mesh geometry.

hexahedron_index must be used like a vector (i.e. hexahedron_index[n])

		const int **&	hexahedron_index
	)		const

Gets the current mesh geometry.

hexahedron_index must be used like a matrix. (i.e. hexahedron_index[cell_index][n], with 0 <= n <= 7)

		PbArrayOfInt &	owner_cells
	)		const

virtual

Gets the list of index of cells that own the list of node "nod_indices" (for example nod_indices can be the list of indices of a facet, an edge...)

Reimplemented from PbMesh.

Assignment operator.
