Simulation techniques are a time- and resource-saving technology for the development of materials, the systematic investigation of property correlations and the testing of material.

Microstructure Simulation and Virtual Material Design

The work within the group of microstructure simulation and virtual material design can be summarized by the overall concept of GeoDict we are developing and marketing software for the optimization of complex three-dimensional geometric structures of porous materials and composites.

Very different material properties are computed in complex 3d structures and successively improved by parameter variation. Currently, the technology is especially applied within projects with respect to the design of components of fuel cells, paper machines, and most different kinds of filters..

Computer Simulation and Virtual Material Design

Properties of existing materials can be described by theories, measured by experiments or characterized by simulations on computer tomographical 3d images (CTs). For new materials, the applicability of theories is sometimes questionable and the development through experiments on prototypes is laborious and expensive. Therefore, there is a great interest in developing new materials by means of computer simulations. For this virtual material design a realistic structure model is required, where the variations one wants to investigate, are described only by a few parameters. These models can be converted to virtual CTs (vCTs).
