The Finite Element Method (FEM) is a calculation method typical for the scientific and technical area. The FE method allows you to calculate complex problems that can hardly be solved by other means.
Since FEM is a numerical method for solving differential equations, it is possible to perform the finite element analyses (FEA) in various physical disciplines. A component subjected to FEA is subdivided into a large number of small finite elements with simple geometry so that the required quantity can be easily calculated. This subdivision provided the name for the numerical technique: Finite Element Method.
In structural engineering, finite element analysis applies FEM as a standard method for computer-aided calculation of beam and plate structures.
The structural analysis program RFEM is the right software for user‑friendly application of the Finite Element Method in structural engineering. Efficient data input and intuitive handling facilitate modeling of simple and large structures. RFEM also provides solutions for structural and dynamic analysis of 3D structures.
RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members.
In addition, it is possible to calculate internal forces as well as support forces. The program also allows you to create combined structures and model solid or contact elements.
Further analysis and design of components consisting of different materials in compliance with various standards can be performed in the corresponding add‑on modules.
For design of various materials such as reinforced and prestressed concrete, steel, aluminium, timber, and glass, there is a wide range of powerful add-on module available for RFEM.
These modules allow you to perform nonlinear, stability and dynamic analyses as well as connection designs and form‑finding processes for cable and membrane structures.
Structural analysis programs by Dlubal Software provide comprehensible structural calculations. They are not a "Black Box". Numerous verification examples available on our website explain how the software works and reveal the calculation methods.
The monastery "Little Flower" was built in 2015, situated in beautiful scenery of green meadows, mountains and crystal-clear lakes.
The little monastery includes 18 bedrooms, a chapel, a dining room, a kitchen, and a conference room.
The "Pneumatic Wedge Method" is a new technique for the construction of double-curved concrete surfaces by means of pneumatic formwork.
Vienna University of Technology used RFEM for the deformation process and checking the final structural conditions.
Baku Flame Towers is a striking complex of high‑rise buildings in Baku, the capital city of Azerbaijan.
The complex consists of three 190‑m‑high towers in shape of a flame as a symbol of several oil wells in the region.
Skywalk Allgäu is a path leading through the treetops of the Allgäu Alps in Southern Germany.
The steel and timber structure of the path about 1,000 m above sea level consists of cable-stayed and suspension bridge constructions.
The Czech research team participates in saving the stone monuments in Angkor, registered as UNESCO World Heritage Site, which are currently largely deteriorated.
To create numerical models and carry out the structural analysis, the structural FEA software RFEM has been used.
The project for designing a filter/dryer device including agitator required a complete stress and deformation analysis in RFEM.
A special design challenge represented the complex modeling of the structue having 1,424 surfaces, 158 solids and 425 members.
The new headquarters of the Baden farmers' association (BLHV) in Freiburg, Germany, is a unique building.
The timber structure is protected by a glass façade to counteract graying caused by weather conditions.
The art project Solhjul ("Sun wheel") by the Danish artist Bo Karberg is inspired by an archaeological find of a 5,000‑year old disk wheel in Pilkmosen near Give, Denmark.
The sculpture of 12m-high steel and glass wheel in Give is now the new symbol of the town.
As a new tool for structural analyses of two-dimensional components, a display function for the FE mesh quality was implemented in RFEM. When you perform an internal check of the generated finite elements for defined criteria, you can graphically display the result. It will be displayed in three different colors to illustrate the different levels of quality. You can edit all values of the criteria and thus adjust them to your individual needs.
Since the release of RFEM 5, the “Result Beam” member type has been available. The result beam is a virtual member that does not have any stiffness nor require any support. It can be used in various situations in order to integrate the results from members, surfaces, and solids, and to display them as member internal forces.
