FE Analysis

Finte Elemente Aggregat

The Finite Element Method (FEM) is a numerical method in which structures, e.g., a machine part, are subdevided into a finite number of geometrically simple elements. The continuum mechanical equations can be formulated more easily for those elements, which typically have simple geometrical shapes. The overall behavior of the structure can be computed from the behavior of the individual elements by appropriate algorithms.

This approach contains some approximations. A simualtion engineer has to have thorough knowledge of the loading conditions of the component and the involved physical effects to set up a useful model. In addition, knowing the basics of Finite Element methods, mainly the understanding of the capabilities of different element types and the knowledge about possible nonlinearities are required for a successful application of this method. The knowledge and experience coming from the successful completition of about 50 projects per year are our basis for creating valid and efficient computational models.

Komplexe Strukturen / complex structures

Complex Structures

Structures of complex geometry or consisting of many parts require great care in setting up corresponding simulation models and in the correct and complete interpretation of results data.

Nichtlinearitäten / Nonlinearities


Physical nonlinearities such as plastic deformation, buckling instabilities or changing contact conditions often complicate the solution of a mechanical problem.


Lightweight Design

The design of lightweight structures is supported heavily by numerical methods. Aircraft, cars, rail vehicles and ships are prime candidates for FE analyses.


Fatigue Assessment

A very common task in our projects is having to find out whether a part or a whole structure has sufficient fatigue strength to withstand the required number of loading cycles.

Dynamisches Verhalten

Dynamic Behavior

Often, the vibration behavior of structures is of interest. The eigenfrequencies of structures can be predicted with high accuracy by means of the finite element method.



Stresses in a part can also arise from inhomogeneous thermal expansion, caused by temperature gradients in the part and/or different material combinations in combination with temperature changes.



In many technical problems structures interact with fluid flow. The flow around or through a structure can cause vibrations or deformations in the structure, which in turn can influence the flow.



In biomechanics CAE Simulation & Solutions focuses on the design of implants and the mechanics of bones. The strain distribution in the bone(s) can be determined by means of Finite Element Method.
