◆ BuildBeam() [1/3]

void chrono::fea::ChBuilderBeamTaperedTimoshenko::BuildBeam ( std::shared_ptr< ChMesh mesh,
std::shared_ptr< ChBeamSectionTaperedTimoshenkoAdvancedGeneric sect,
const int  N,
const ChVector3d  A,
const ChVector3d  B,
const ChVector3d  Ydir 
)

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

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

Parameters
meshmesh to store the resulting elements
sectsection material for beam elements
Nnumber of elements in the segment
Astarting point
Bending point
Ydirthe 'up' Y direction of the beam

◆ BuildBeam() [2/3]

void chrono::fea::ChBuilderBeamTaperedTimoshenko::BuildBeam ( std::shared_ptr< ChMesh mesh,
std::shared_ptr< ChBeamSectionTaperedTimoshenkoAdvancedGeneric sect,
const int  N,
std::shared_ptr< ChNodeFEAxyzrot nodeA,
const ChVector3d  B,
const ChVector3d  Ydir 
)

Add beam FEM elements to the mesh to create a segment beam from one existing node to a point B, using ChElementBeamTaperedTimoshenko type elements.

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

Parameters
meshmesh to store the resulting elements
sectsection material for beam elements
Nnumber of elements in the segment
nodeAstarting point
Bending point
Ydirthe 'up' Y direction of the beam

◆ BuildBeam() [3/3]

void chrono::fea::ChBuilderBeamTaperedTimoshenko::BuildBeam ( std::shared_ptr< ChMesh mesh,
std::shared_ptr< ChBeamSectionTaperedTimoshenkoAdvancedGeneric sect,
const int  N,
std::shared_ptr< ChNodeFEAxyzrot nodeA,
std::shared_ptr< ChNodeFEAxyzrot nodeB,
const ChVector3d  Ydir 
)

Add beam FEM elements to the mesh to create a segment beam from one existing node to another existing node, using ChElementBeamTaperedTimoshenko type elements.

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

Parameters
meshmesh to store the resulting elements
sectsection material for beam elements
Nnumber of elements in the segment
nodeAstarting point
nodeBending point
Ydirthe 'up' Y direction of the beam

◆ GetLastBeamElements()

std::vector<std::shared_ptr<ChElementBeamTaperedTimoshenko> >& chrono::fea::ChBuilderBeamTaperedTimoshenko::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.

◆ GetLastBeamNodes()

std::vector<std::shared_ptr<ChNodeFEAxyzrot> >& chrono::fea::ChBuilderBeamTaperedTimoshenko::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.
