Member Function Documentation

void chrono::fea::ChBuilderCableANCF::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChBeamSectionCable >	sect,
		const int	N,
		const ChVector<>	A,
		const ChVector<>	B
	)

Adds cable FEM elements to the mesh to create a segment beam from point A to point B, using ChElementCableANCF type elements.

Before running, each time resets lists of beam_elems and beam_nodes.

Parameters

mesh	mesh to store the resulting elements
sect	section material for cable elements
N	number of elements in the segment
A	starting point
B	ending point

void chrono::fea::ChBuilderCableANCF::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChBeamSectionCable >	sect,
		const int	N,
		const ChVector<>	A,
		const ChVector<>	B,
		std::vector< std::vector< int >> &	nodes,
		std::vector< std::vector< int >> &	node_nbrs
	)

Adds cable FEM elements to the mesh to create a segment beam from point A to point B, using ChElementCableANCF type elements.

Before running, each time resets lists of beam_elems and beam_nodes. This version also returns connectivity information.

Parameters

mesh	mesh to store the resulting elements
sect	section material for cable elements
N	number of elements in the segment
A	starting point
B	ending point
nodes	node indices for all elements
node_nbrs	neighbor node indices (connectivity)

std::vector<std::shared_ptr<ChElementCableANCF> >& chrono::fea::ChBuilderCableANCF::GetLastBeamElements ( )

inline

Access the list of elements used by the last built beam.

It can be useful for changing properties afterwards. This list is reset all times a BuildCable function is called.

std::vector<std::shared_ptr<ChNodeFEAxyzD> >& chrono::fea::ChBuilderCableANCF::GetLastBeamNodes ( )

inline

Access the list of nodes used by the last built beam.

It can be useful for adding constraints or changing properties afterwards. This list is reset all times a BuildCable function is called.
