Product Feature

By activating the Form-Finding add-on in the Base Data, a form-finding effect is assigned to the load cases with the load case category "Prestress" in conjunction with the form-finding loads from the member, surface, and solid load catalog. Such a prestress load case thus mutates into a form-finding analysis for the entire model with all member, surface, and solid elements defined in it. The form-finding of the relevant member and membrane elements amid the overall model is carried out via special form-finding loads and regular load definitions. The form-finding loads describe the expected state of deformation or force after the form-finding in the elements, and the regular loads describe the external loading of the entire system.

Additional Analysis

The Form-Finding add-on finds the optimal shape of members subjected to axial forces and tension-loaded surface models. The shape is determined by the equilibrium between the member axial force or the membrane stress and the existing boundary conditions.
