	)

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. damping

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
Poisson_effect	set true to evaluate poisson effects
grav	set true to apply gravity force

std::vector<std::shared_ptr<ChElementBeamANCF> >& 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.
