Flow and Material Simulation Flow and Material Simulation Industrially applicable multi-scale simulation and customized software solutions our simulation methods with suitable data space descriptions and database concepts. The simulation-based design of complex flow processes deals with the associated manufac- turing processes such as coating, mixing, foaming, injection, filtration and separation. The main focus of industrial applications is on filtration and separation processes and, in ad- dition, the product design of filtration plants. Reactive processes such as catalytic filtration, polyurethane foaming or the electrochemical processes in battery and fuel cells are correctly represented in our simulation programs. In combination with the corresponding digital material data spaces, we create multi-scale digital twins for filter elements, battery cells, textile products and lightweight components, among others, which enable virtually support- ed product design, production and operation- al control.

In- quiries concern, for example, the production and functionalization of filter materials and technical filter systems, battery or fuel cells, technical textiles for hygiene products or sports textiles, foams for insulation and damping and fiber- and particle-reinforced lightweight com- ponents. Our unique position is characterized by the development, provision and specific applica- tion of industrially suitable multiscale and mul- tiphysics methods, the development of digital material and product twins and company-spe- cific software solutions. Our simulation tools use the latest research results such as model order reduction techniques, automatic param- eter identification, machine learning, modern software and database concepts to increase efficiency. Microstructure simulation and virtual material design enable numerical simulation and opti- mization of functional properties of porous materials and composites. Our highly efficient micromechanical methods for material design of fiber-reinforced composites, foams and technical textiles are in great demand. The ef- ficient integration of micromechanics and dy- namics as a multiscale material model for CAE software enables the detailed prediction of lo- cal crash, damage or even creep behavior.
