Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
RF‑FORM‑FINDING searches for shapes of structures subjected to tension or compression, such as membrane and cable structures. The shape is calculated by the equilibrium between the surface stress (specified prestress and additional load such as self‑weight, pressure, etc.) and the given boundary requirements. The prestressed model is afterwards used as the initial state for all subsequent calculations.
RF‑CUTTING‑PATTERN generates and organizes cutting patterns for membrane structures. Boundary conditions of the cutting patterns on curved geometry are determined by boundary lines and independent planar cutting lines or geodesic cutting lines. The flattening process is performed according to the minimum energy theory.
The RF-MAT NL add-on module allows for consideration of nonlinear material behavior in RFEM.
It offers the 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" (RF-MAT-NL add-on module required). This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.
For structural analysis and design of tensile membrane structures or their substructures, find more useful add‑on modules under the Steel Structures as well as Aluminum and Light-Weight Structures industry.
A unique roof structure was built for the main bus station in Aarau, Switzerland in 2013.
The canopy has a cloud-like shape and contains the largest single‑chamber cushion in the world. The ETFE cushion has a volume of 63,919.55 ft³ and covers an area of 11,517.38 ft².
Allianz Arena is a soccer stadium in Munich, Germany, which hosted the opening match of the 2006 FIFA World Cup.
The translucent exterior facade of the stadium emits light in various colors and thus makes the whole arena building very special.
The Eden Project is a complex of two biomes and outdoor gardens with plants from many diverse climates and environments.
The biome is a steel frame structure with cladding panels consisting of triple-layered membrane cushions made of ETFE foil.
A giant wooden airship “suspended” above the Centre for Contemporary Art in Prague, Czech Republic, has been opened to the public in December 2016.
The unique timber and steel airship structure “Gulliver” will serve as a space for literature.

Dlubal Software is a member of the TensiNet Association.
This doctoral thesis by Rostislav Lang deals with the design and analysis of membrane structures using FEA software.
RFEM provides the option to couple surfaces with the stiffness types "Membrane" and "Membrane-Orthotropic" with the material models "Isotropic-nonlinearly elastic 2D / 3D" and "Isotropic Plastic 2D / 3D" (add-on module RF-MAT NL required).
This functionality allows you to simulate the nonlinear strain behavior of z. Eg ETFE films.
