The geometry of a structure is schematized as follows:
- MatrixFrame® 2D and 3D frameworks / frameworks and 1D / 2D beams / beam gratings are schematized according to bar models, consisting of nodes and bars.
- MatrixFrame® FEM plates and FEM walls are schematized according to plate models, consisting of a closed polygon of points and lines.
This chapter describes the entry of bar models.
For plate models, go to FEM plates and FEM walls.
