Numerical simulation for structural mechanics using the finite element method (FEM) and fluid mechanics (CFD) has long been established at the DITF and is used to support research by simulating textile manufacturing processes, investigating and representing phenomenological processes, and improving understanding of complex textile material behavior. Simulation models with a very high level of detail are developed, which include threads and filaments.
The main areas of focus are:
- Simulation of manufacturing processes – virtual prototyping
- Development of simulation models for calculating the complex properties of textile-based materials
- Simulation of loads such as draping and impact (virtual testing)
- Investigation of phenomenological processes
- Simulation of fiber composite applications
- Flow simulations (rooms, air jets, fiber transport in air flows)
The special testing and measuring equipment for material analysis, parameter determination, and validation of numerical simulation (e.g., micro computed tomography with in situ load test stand, particle image velocimetry, contactless strain measurement ARAMIS, high-speed cameras, impact test stand) are indispensable advantages of the simulation department at the DITF Competence Center for Staple Fiber, Weaving, and Simulation.
Research licenses for calculation software from Ansys (LS-DYNA and Fluent), BETA CAE, and open-source software such as OpenFOAM are used to process publicly funded projects.
If industry support is desired with calculations using LS-DYNA and Fluent, etc., commercial licenses are required and must be taken into account.
