The geometry of a structure is schematized as follows:
- MatrixFrame® 2D and 3D frames and 1D/2D beams and grillages are schematized using bar models, consisting of nodes and bars.
- MatrixFrame® FEM plates and FEM walls are schematized using plate models, consisting of a closed polygon defined by points and lines.
This chapter describes the input of bar models.
For plate models, refer to the section FEM plates & walls.
