Member Function Documentation

GetNormals()

virtual void chrono::fea::ChBeamSectionShapeCircular::GetNormals ( unsigned int  i_line, std::vector< ChVector3d > &  mnormals  ) const

inlineoverridevirtual

Compute the normals (in the reference of the section) at each point.

Note: mnormals must already have the proper size.

Implements chrono::fea::ChBeamSectionShape.

GetNumLines()

virtual unsigned int chrono::fea::ChBeamSectionShapeCircular::GetNumLines ( ) const

inlineoverridevirtual

Get the number of lines making the profile of the section, for meshing purposes.

C0 continuity is required between lines, C1 also required within each line. Ex. a circle has 1 line, a cube 4 lines, etc. Sharp corners can be done mith multiple lines.

Implements chrono::fea::ChBeamSectionShape.

GetNumPoints()

virtual unsigned int chrono::fea::ChBeamSectionShapeCircular::GetNumPoints ( unsigned int  i_line ) const

inlineoverridevirtual

Get the number of points to be allocated per each section, for the i-th line in the section.

We assume one also allocates same number of 3d normalss.

Implements chrono::fea::ChBeamSectionShape.

GetPoints()

virtual void chrono::fea::ChBeamSectionShapeCircular::GetPoints ( unsigned int  i_line, std::vector< ChVector3d > &  mpoints  ) const

inlineoverridevirtual

Compute the points (in the reference of the section).

Note: mpoints must already have the proper size.

Implements chrono::fea::ChBeamSectionShape.
