Member and Surface Configurations for Stress-Strain Analysis
This article shows how to manage the input data for member and surface design configurations within the Stress-Strain Analysis add-on.

Compared to the RF-FORM-FINDING add-on module (RFEM 5), the following new features have been added to the Form-Finding add-on for RFEM 6:
- Specification of all form-finding load boundary conditions in one load case
- Storage of form-finding results as initial state for further model analysis
- Automatic assignment of the form-finding initial state via combination wizards to all load situations of a design situation
- Additionally form-finding geometry boundary conditions for members (unstressed length, maximum vertical sag, low-point vertical sag)
- Additional form-finding load boundary conditions for members (maximum force in member, minimum force in member, horizontal tension component, tension at i-end, tension at j-end, minimum tension at i-end, minimum tension at j-end)
- Material type "Fabric" and "Foil" in material library
- Parallel form-findings in one model
- Simulation of sequentially building form-finding states in connection with the Construction Stages Analysis (CSA) Add-On
- 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?
