Data structure for definition of 2D and 3D beam (cross) section geometrical properties. Used for visualization and contact.
BeamSectionGeometry has the following items:
- crossSectionRadiusY [type = UReal, default = 0.]:c\_Y\, [SI:m] Y radius for circular cross section
- crossSectionRadiusZ [type = UReal, default = 0.]:c\_Z\, [SI:m] Z radius for circular cross section
- crossSectionType [type = CrossSectionType, default = CrossSectionType::Polygon]:Type of cross section: Polygon, Circular, etc.
- polygonalPoints [type = Vector2DList]:{\mathbf{p}}\_{pg}\, [SI: (m,m) ] list of polygonal (Y,Z) points in local beam cross section coordinates, defined in positive rotation direction
