Steering the Future of Mobility with thyssenkrupp Presta AG

thyssenkrupp case study

Ansys helps thyssenkrupp Presta AG to realize complex 3D digital versions of its components and lead the evolution of the automotive sector.

"Ansys Mechanical provides the ability to model the realistic and complex details of injection molded plastics, like the orientation of fibers and the presence of injection stresses in the parts, which significantly increases the accuracy of our engineering developments."

—Francesco Fiorini, structural and durability engineer at thysssenkrupp Presta AG

All products have an environmental impact, a fact customers are increasingly aware of as they take an interest in their carbon footprints. In the automotive industry, there is a global push to reach zero vehicle emissions by 2050 to satisfy consumer demand and increasingly stricter environmental laws. To do so, leading vehicle manufactures and their partners are embracing lightweighting and electrification. Composite materials are key to making vehicles lighter so they can use smaller engines that consume less energy and produce fewer emissions. For the high-volume production models (body panels, frames, housings), an increasingly adopted technique is the manufacturing of critical components through injection molding with short-fiber reinforced plastics.

Thyssenkrupp Presta is leveraging its longstanding competencies in materials, components and systems to lead automotive digital transformation processes. Ansys Mechanical’s short fiber reinforced composite workflow helped thyssenkrupp Presta reach the targeted 50% weight reduction with respect to the original metal part to meet mechanical performance and OEMs requirements. The adoption of an innovative and lightweight plastic housing for its steering system supports both the ecological and economical goals of thyssenkrupp Presta and helps the company lead the evolution of the steering systems for the automotive market of tomorrow.

  • High Performance Computing

Carry out acoustics simulations to understand the vibroacoustic behavior of systems, with or without structural pre-loading. Including pre-loading adds more fidelity and means that self-weighted, bolted assemblies — or even squealing brakes — can be simulated. 

Nonlinear simulation also takes into account contact and large deflection of parts moving around relative to each other, either with or without friction.

It can simulate everything from a bonded contact that treats joints between parts as if they are glued or welded together to contact interfaces that allow parts to move apart and together with or without frictional effects. Being able to simulate contact correctly means that you can simulate the change in load paths when parts deform and confidently predict how assemblies will behave in the real world.

Any model in Ansys Mechanical can be used to drive a parametric optimization. Shape and topology optimization capabilities allow creation of efficient geometries, which can be taken back to CAD for production or further simulation work. Additive manufacturing, lightweighting and robust design are excellent use cases for this technology.

With Ansys Mechanical, you can read in power losses or calculated temperatures from other analysis systems or files, which means that CFD or electromagnetic simulations can be a starting point for thermal analysis. It is also possible to account for fluid flow through pipes and heat generated from friction between parts. All these capabilities give you more accurate simulations and better results.

You can also add user-defined material models, if needed. Granta Materials Data for Simulation provides instant, clickable access to the materials property data you need, eliminating data search time and input errors. Material Designer can easily create representative volume elements (RVE’s) based around lattice, fiber, weave or user-created geometries to facilitate multiscale modeling of complex material structures.

Ansys Mechanical includes capabilities to model layered composites through the connection with Ansys PrepPost (ACP) and short fiber composites through the connection with upstream manufacturing simulation tools and the material behavior obtained from Material Designer, the Ansys tool for multiscale homogenization of materials microstructures.  

You can generate composite models for implicit and explicit structural, thermal and fluid simulations. Ansys Composite PrepPost (ACP) is the Ansys dedicated tool for modeling composite layups and failure analysis. ACP provides efficient layup and best-in-class solid element modeling capabilities and a platform that offers many ways to exchange model information. It supports the vendor-independent HDF5 composite CAE file format for communication with third-party tools, many of them dedicated and related to composites manufacturing. Beyond the modeling of composite structures, Ansys Composite Cure Simulation (ACCS), simulates curing during manufacturing processes. ACCS is an extension for Ansys Mechanical and it helps you to simulate the curing process of a part and predicts residual stresses and process-induced distortions for realizing compensation analyses.  

These include SPARs, FPSOs, semi-submersibles, tension leg platforms, ships, renewable energy devices and breakwaters. Our product, Ansys Aqwa, has been used extensively in the oil and gas, renewable and general engineering sectors to model installation and use of equipment in open water as well as in harbors or sheltered locations.

One-way coupling solves the initial CFD or Ansys Mechanical simulation and automatically transfers and maps the data to the other system. In a two-way coupling simulation, the fluid and structural simulations are set up and solved at the same time and data is automatically transferred between two solvers to achieve robust and accurate results.

Journaling and scripting capabilities enable quick development and easy education of new scripts.

There are several ways to open and access APDL, including through Ansys Workbench, the Start Menu, the APDL product launcher, and the command line.

The preferred method to open APDL is through the product launcher from the Windows Start Menu, so that a user can customize the product settings, including simulation environment and license, working directory, customization, high-performance computing setup, and more.

Opening through Workbench is recommended if the user intends to share the files from MAPDL with other Workbench models. Opening through the Windows Start Menu launches a standalone MAPDL session using the default product settings.

Symmetry in Ansys Mechanical enables users to only model a portion of the structure they are simulating to achieve faster simulation and post-processing results. Users can implement Symmetry if the geometry, material orientation, loading, and expected response all exhibit symmetry about the same planes.

To use Symmetry in Ansys Mechanical, you can either select the Model folder under your current project, navigate to the Model tab, and select Symmetry, or right-click on the Model folder and choose Insert then Symmetry. Both options above will insert a symmetry folder object where different types of Symmetry can be added.

Based on analysis type and symmetry needs, the following Symmetry objects can be inserted: symmetry region, linear periodic, periodic region, cyclic region, and pre-mesh cyclic region.

Current customers can download Ansys Mechanical from the Download Center in the Ansys Customer Portal.


If you are a student, you can download our free student software and use it along with our free courses, support community, and a wealth of student-focused tutorials.


Ansys Parametric Design Language, or APDL, is a powerful, structured scripting language used to interact with the Ansys Mechanical solver. Mechanical APDL, or MAPDL, is a finite element analysis program driven by APDL.

Both APDL and MAPDL can be used for various tasks ranging from creating geometries to setting up sophisticated solver settings for highly complex analyses. APDL provides access to advanced features and capabilities of Ansys Mechanical that may not be exposed or available through the graphical user interface (GUI).

With APDL, users can create custom input files, define material properties, apply boundary conditions and loads, customize the solution process, and more to tailor the analysis to their specific needs.
