Testing and calculation are complementary areas for the verification and optimization of constructions. Calculation helps to get better products faster, which can meet the requirements placed on them in terms of function, reliability and price.
Using simulation in the right place reduces your costs!
Our latest customer satisfaction analysis shows that companies that primarily bring new products onto the market will make use of the possibilities of simultaneous engineering which will be involved in product development and process optimization in the future. As various studies have shown, both the total time to market and the total costs for product development are reduced, even if the costs in the development area and in construction initially increase by approx. 50 – 100%.
The finite element method (FEM for short) is a numerical calculation method. The problem or the calculation is divided into a finite number of elements. The equations (mostly differential equations) are then solved for each of these elements. The results provide information about the entire calculation. The number of elements determines the accuracy of the overall results. The method is used in engineering both in structural mechanics and in fluid mechanics.
Structural mechanics is the calculation of deformations, deflections, and internal forces or stresses within structures, either for design or for performance evaluation of existing structures. It deals with the strength calculation of components, material molded parts, component groups, etc., which consist of solid materials such as steel, aluminum, other metal, plastic, rubber, composite material, concrete, wood, glass or others.
Structural mechanics is a technical discipline in which mechanical solid models are created, the solid components to be examined are subdivided into finite substructures and subjected to external mechanical or thermal loads (using the free-cutting principle in the case of vector-valued and directional quantities). As a rule, the contours of the finite individual elements of the substructures correspond to elementary geometric shapes. The interfaces of the individual elements of the finite substructures can then be used to more precisely calculate sizes and states vertically, tangentially or at an angle to these limits in the interior of the solid-state components and thus to gain information about conditions inside the component. Structural mechanics is an interdisciplinary engineering field, which has applications in mechanical engineering (and in particular in vehicle construction, but also in many other branch disciplines), in construction (and in particular in steel construction), in aerospace technology and in defense technology.

Computational fluid dynamics (CFD) is an established method of flow simulation. It aims to solve fluid mechanical problems approximately using numerical methods. The model equations used are mostly Navier-Stokes equations, Euler equations or potential equations. The motivation for this is that important problems such as the calculation of the drag coefficient very quickly lead to non-linear problems that can only be solved precisely in special cases. The numerical flow mechanics then offers a cost-effective alternative to wind tunnel tests.
The internationally used abbreviation CFD has been used since a conference of the AIAA in 1973. The use of CFD as an aircraft design tool was also established there.
