I cannot define the prestress separately for warp and weft in RF‑FORM‑FINDING. How can I activate it?
Answer
The warp and weft directions are linked to the axes of the surface. The default setting allows you to only apply isotropic prestress. If the axes are aligned, the orthotropic or radial prestress will be available as well.
The video shows the procedure.

The RF‑FORM‑FINDING add‑on module can be activated in the ‘Edit Model - General Data’ window, ‘Options’ tab. By activating the module, a new RF‑FORM‑FINDING load case is created and an additional menu appears in the main program, allowing for the definition of prestress conditions for membrane and cable elements.

Display of Topology on Deformed Structure
With the activated option "Topology on form-finding shape" in the Project Navigator - Display, the model display is optimized based on the form-finding geometry. For example, the loads are displayed in relation to the deformed system.
Frequently Asked Questions (FAQ)
- How do I model a suspended membrane roof structure with line supports?
- How do I model a tent roof with two cone tips?
- How is an inflatable object simulated in RFEM?
- A cable structure model created in RFEM 5.13 cannot be calculated in the current version of the program. The program displays a message that "Stiffness matrix is singular," although it could be calculated in the original version. How can I fix this?
- How is it possible to create the cutting pattern geometry for a decorative sticker on a biaxially curved membrane roof?
- Why does the form-finding not work for the "Cable on Pulleys" member type?
- How are the properties of the elasticity and shear modulus of a membrane fabric with the usual force/length syntax transformed into the general force/surface syntax to be entered in RFEM?
- It seems that the members stay not deformed after my RF-FORM-FINDING calculation. What went wrong?
- How can I influence the sag of the found shape in RF‑FORM‑FINDING?
- Why is the membrane constricted so much during the form-finding? I obtain very large deformation values.
