Form-Finding | Input
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.

RFEM 6 includes the Form-Finding add-on to determine the equilibrium shapes of surface models subjected to tension and members subjected to axial forces. Activate this add-on in the model's Base Data and use it to find the geometric position in which the prestress of lightweight structures is in equilibrium with the existing boundary conditions.

How do I create a user-defined fabric?
- Why do the results in a modal analysis differ between the initial prestress and the surface load?
- Although I modeled two identical systems, I got a different shape. Why?
- I want to create a mapped mesh for a circular hole plate. Is it possible to generate such a mesh in RFEM?
- How is it possible to make factorized combinations of a dead load in the context of form‑finding?
- It seems that the members stay not deformed after my RF‑FORM‑FINDING calculation. What did I wrong?

Can I export my cutting pattern?

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.
