Detailed Description

A in-core implementation of the b2dbv3::Domain. All the Element, Node and ElementProperty objects are loaded in memory at theInitialisation of the object with the database.

Note

that the processing of the element types defined inside enum element_type_t takes place using a binary interpretation of the different values. Do not assume a simple sequential ordering when adding further element types!

get_adjacent_elements()

void b2000::b2dbv3::Domain::get_adjacent_elements ( std::pair< int, const Node *const * >  node_list, std::vector< AdjacentElement > &  adjacent_elements  )

inlineoverridevirtual

Get the list of elements that are adjacent to all the Node instances given as argument.

Parameters

node_list	A pair (first, second) with first being the number of nodes and second a pointer to an array of Node pointers (input).
adjacent_elements	A vector of containing information on adjacent elements. Each entry corresponds to one Element.

The AdjacentElement::internal_node_id_list contains the node-internal ID's of the nodes given in node_list that

Returns

The type of connectivity of FE elements present in the domain (1D, 2D, 3D, etc.). This function is called by the Solver instance (for the sparse matrix solver). Depending on this value, the Solver decides what graph partitioning algorithm to use for the symbolic factorization.
