- 4. Finite element analysis (FEA) - node and beam (1d) Model setup (nodes and beam centerlines) Beam Element (2D Line) Beam elements are long and slender, have three nodes, and can be oriented anywhere in 3D space Beam corss section definition Load application and deflection Columbia University GSAPP ARCH A4845: Generative design
- 5. Finite element analysis (FEA) - mesh (2d/3d) Surface Mesh Solid (Volumetric) Mesh Membrane Element (2D Planar) Membrane Elements are 3 or 4 node 2D elements that can be oriented anywhere in 3D space. 3D Tetrahedra Element (3D Solid) Tetrahedra elements are normally used to model solid objects for which plate elements are not appropriate Columbia University GSAPP ARCH A4845: Generative design
