Research Area B: Advanced Mechanics of Multi-scale and Multi-field Problems
No matter whether solid, liquid or gaseous, SimTech studies materials in all their aggregate states. Scientists use methods of numerical mathematics such as the finite element method (FEM) and the discrete element method (DEM) to describe materials comprehensively. They are simulated with their physical, chemical and – where appropriate – together with their biological properties – as accurately as necessary and as fast as possible.
The aim of SimTech’s engineering scientists is to propose really practicable solutions. This means that computing only takes place on the smallest scales when this is important for the topic under investigation. Mathematical homogenisation techniques are used to transfer processes from microscale (molecular and particle simulations) to macroscopic scales. The SimTech team develops new formula and simplifies and optimises already existing ones. Large-scale work pieces, such as a bridge, or processes, such as the formation of a crack therein, can then be described better and faster than ever before.
Design of innovative high-tech materials
However, our aim is not only to describe existing materials and to learn their load limits. With the aid of simulations, innovative high-tech materials will be designed by computer scientists for future use in fields ranging from geo- and biomechanics, over medicine and environmental protection techniques as well as construction and mechanical engineering right up to the field of aviation and aerospace. Prominent examples are heavy duty bridges or light-weight roofs for airports and other large-scale plants.
A question of feasibility
Feasibility studies on how to pump environmentally unfriendly gases into deep layers of earth benefit from SimTech’s simulations just as much as does the medical profession as a whole. For example, SimTech researchers are simulating the human spine together with the surrounding muscles, sinews and ligaments. Such work opens up new perspectives on diagnosis and therapy options.
