Our department »Transport Processes» has been simulating the dynamics of fibers in turbulent flows with the software FIDYST (Fiber Dynamics Simulation Tool) for years. In the past, the focus was on energy consumption and the deposition of the fibers on the conveyor belt.
In the end, however, the mechanical and thermal properties as well as the quality of the nonwovens are decisive for their sale. For the simulation of these material properties, our »Flow and Material Simulation« department has therefore developed the digital material laboratory GeoDict. It has been distributed and further developed worldwide by the spin-off Math2Market GmbH since 2011. The software can be used, among other things, to calculate nonwoven product properties such as permeability, filtration efficiency, acoustic absorption, conductivities, stiffnesses or even mechanical resilience.
In the ViDestoP project, it was possible to combine these two simulation tools into an integrated digital twin for nonwovens production. This means that our researchers combined the digital twins for the process (FIDYST) and the material properties (GeoDict) in several work steps.
