class FiniteElement(elem_type)[source]¶

Bases: object

Quadrilateral/Hexahedral finite element.

_elem_type¶

Finite element type.

Type:: str

_n_dim¶

Number of spatial dimensions.

Type:: int

_n_nodes¶

Number of nodes.

Type:: int

_n_edges¶

Number of edges.

Type:: int

_n_edge_nodes¶

Number of nodes per edge.

Type:: int

_nodes_matrix¶

Element nodes matrix (numpy.ndarray[int](n_dim*(n_edge_nodes,))) where each element corresponds to a given node position and whose value is set either as the node label (according to adopted numbering convention) or zero (if the node does not exist). Nodes are labeled from 1 to n_nodes.

Type:: numpy.ndarray(2d or 3d)

_available_elem_type()[source]¶: Get available finite element types.

_is_available_elem_type(elem_type)[source]¶: Check if finite element type is available.

_set_elem_type_attributes(self)[source]¶: Set finite element type attributes.

get_n_dim(self)[source]¶: Get number of spatial dimensions.

get_n_edge_nodes(self)[source]¶: Get number of nodes per edge.

get_nodes_matrix(self)[source]¶: Get element nodes matrix.

get_node_label_index(self, label)[source]¶: Get node label index on element nodal matrix.
