Research Focus
The focus of research is on the development of methods and processes for the simulation and optimization of complex systems and computer-aided processes in product development. Key aspects and subtopics are:
- Coupled simulation and optimization methods
- Structural optimization
- Lightweight design
- Multiphysics
- CFD flow simulation
- Robust design
Research Approach
Due to the often very complex interactions in real systems, numerical approaches for the description of these systems by individual standard tools are no longer to be used.
By coupling methods, efficient tools can be created that are solutions of these complex problems and thus support the product developer in the design synthesis.
Examples for coupling methods
- Structure optimization taking into account production restrictions
- Multiphysical structure simulation with wear simulation
- CFD flow simulation with thermomechanics
Service Offer
We are your contact for questions concerning the design, dimensioning and optimization of components and systems.
We develop customised simulation and optimization tools for you.
The tools developed are based on established and commercially available methods, which ensure good software availability and short employee training periods.
Thanks to virtual product development, we create sophisticated and innovative products together with you.
For the validation, IPEK can rely on modern test benches, high-quality measurement technology and experience.
