void chrono::fea::ChBuilderBeamIGA::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChBeamSectionCosserat >	sect,
		const int	N,
		const ChVector<>	A,
		const ChVector<>	B,
		const ChVector<>	Ydir,
		const int	order = `3`
	)

Add beam FEM elements to the mesh to create a segment beam from point A to point B, using ChElementBeamIGA type elements.

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

Parameters

mesh	mesh to store the resulting elements
sect	section property for beam elements
N	number of elements in the segment
A	starting point
B	ending point
Ydir	the 'up' Y direction of the beam
order	the order of spline (default=3,cubic)

void chrono::fea::ChBuilderBeamIGA::BuildBeam	(	std::shared_ptr< ChMesh >	mesh,
		std::shared_ptr< ChBeamSectionCosserat >	sect,
		geometry::ChLineBspline &	spline,
		const ChVector<>	Ydirn
	)

Add beam FEM elements to the mesh to create a spline beam using ChElementBeamIGA type elements, given a B-spline line in 3D space.

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

Parameters

mesh	mesh to store the resulting elements
sect	section material for beam elements
spline	the B-spline to be used as the centerline
Ydirn	the 'up' Y direction of the beam

std::vector<std::shared_ptr<ChElementBeamIGA> >& chrono::fea::ChBuilderBeamIGA::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<ChNodeFEAxyzrot> >& chrono::fea::ChBuilderBeamIGA::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.
