Activating 'Show Form-Finding' in the shortcut menu leads to an automatic preliminary form-finding according to the saved form-finding properties when you change the structure of membrane surfaces. This interactive graphics mode is based on the force density method.
More Information FAQ![Foil Cushion with Material Model Isotropic Plastic 2D/3D](/en/webimage/006832/497212/Form-finding_de.png?mw=512&hash=78051e4822ef57bc2068122c169039849806ee35)
In RFEM, there is an option to couple surfaces with the stiffness types "Membrane" and "Membrane Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (add-on module RF-MAT NL erforderlich).
This functionality enables simulation of the nonlinear strain behavior of ETFE foils, for example.

The "Base Plate" component allows you to design base plate connections with cast-in anchors. In this case, plates, welds, anchorages, and steel-concrete interaction are analyzed.
