St

Tailored for 3D linear structural analysis, and the frame element includes options for Saint Venant torsion, warping torsion, geometric stiffness, and shear deformation. It has a growing element library that will include plane membranes, plates, shells, and brick elements. A unique future feature of St is the link with Building Information Models (BIMs) via an Industry Foundation Class (IFC) import option, together with an extended element formulation for composite structural members that includes code checks, damage predictions, and explicit description of model uncertainty.
