void chrono::fea::ChBuilderBeamANCF::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChMaterialBeamANCF >	mat,
		const int	N,
		const ChVector<>	A,
		const ChVector<>	B,
		const double	h,
		const double	w,
		const ChVector<>	DIR,
		const ChVector<>	CUR,
		const bool	grav = `false`,
		const double	damp = `0`
	)

Add beam 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
mat	material for beam elements
N	number of elements in the segment
A	starting point
B	ending point
h	height
w	width
DIR	initial nodal direction
CUR	initial nodal curvature
grav	set true to apply gravity force
damp	damping

std::vector<std::shared_ptr<ChElementBeamANCF_3333> >& chrono::fea::ChBuilderBeamANCF::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 BuildBeam function is called.

std::vector<std::shared_ptr<ChNodeFEAxyzDD> >& chrono::fea::ChBuilderBeamANCF::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 BuildBeam function is called.
