Many companies either simulate or prototype, rarely offering both in an integrated way.
Project durations often stretch far beyond the initial schedule.
Track records in handling complex, cross-industry projects are limited.
Engineering is often treated as an isolated task instead of a holistic development process.

FAQ
What are the advantages of CFD simulations compared to physical prototypes?
CFD simulations (Computational Fluid Dynamics) make it possible to virtually analyze flows, heat transfer, aerodynamic effects, and even combustion mechanisms. This allows weak points to be identified early on and different design variants to be compared efficiently – without the need to build costly prototypes every time. As a result, development times are significantly reduced, sources of error are minimized, and investments are secured more effectively. CFD simulations can also be reused for future product generations, drastically reducing development time and optimizing functionality.
Result: Faster development, lower costs, improved product performance.
How does Felsaris support the development and optimization of prototypes?
We guide companies from the initial idea through to pre-series production. This includes CAD design, reverse engineering, additive and conventional manufacturing methods, FEM and CFD simulations, as well as the creation of bills of materials and cost estimates. By combining digital and physical methods, functional prototypes can be developed efficiently and tested quickly. This approach minimizes risks in product development and provides a solid foundation for investment decisions.
Result: Market-ready prototypes in less time and with higher planning reliability.
What role does Artificial Intelligence (AI) play in Felsaris’ development processes?
We use AI strategically to accelerate development cycles and increase the accuracy of simulations. Surrogate models replace traditional trial-and-error approaches and enable fast, data-driven predictions. At the same time, AI algorithms support pattern recognition in large datasets and help identify the optimal design with fewer iterations. This leads not only to higher efficiency but also to a significant reduction in costs.
Result: Shorter development times, fewer physical prototypes, optimal design solutions through advanced optimization algorithms.
What typical results can be achieved through flow optimization?
Flow optimization improves the efficiency, stability, and reliability of products. Using CFD analyses, pressure losses can be reduced, flow separation can be prevented, and aerodynamic properties as well as combustion emissions can be optimized. This not only increases overall performance but also reduces energy losses and component stress. Particularly in the fields of automotive and mechanical engineering, such improvements create a significant competitive advantage.
Result: Higher efficiency, improved product performance, reduced operating costs, and shorter development cycles.
How does Felsaris contribute to emission reduction in engine development?
We combine high-precision combustion simulations with chemical reaction modeling to minimize pollutants such as NOx, CO, and unburned hydrocarbons. In addition, we develop low-emission combustion systems for hydrogen, methanol, and ammonia. This enables our customers to meet stringent regulatory requirements while accelerating the transition to sustainable fuels.
Result: Clean combustion systems with validated emission performance.
What happens with the simulation results after the project?
We deliver the results in the format best suited to your needs, either as a traditional written report or as a custom built interactive website (technical wiki). Additionally, we can provide expert video recordings that guide you step by step through the outcomes. For larger and more complex projects, we are able to develop predictive AI surrogate models, giving you the freedom to explore an unlimited number of design variations within the defined parameter space. If requested, we also empower your in house engineering teams to continue working with and expanding upon the simulation results independently.
Result: Flexible result delivery, advanced tools for ongoing design exploration, and long term usability for your engineering team.
Can you manufacture my prototype parts directly?
Yes. Through our network of trusted partners, we provide both conventional manufacturing methods such as turning and 5 axis milling, as well as additive manufacturing using FDM and resin based SLA or DLP processes. This ensures high quality prototype parts delivered quickly and precisely according to your design requirements.
Result: Fast, precise, and reliable prototype manufacturing.
Can existing combustion engines be converted to hydrogen operation?
Yes, this is one of Felsaris GmbH’s key strengths. Using 3D scanning and reverse engineering, we capture existing engines in full detail and develop new, hydrogen-compatible components based on them. These components are designed using state-of-the-art CAD and CFD simulations and then validated through real test bench trials. The result is high-performance hydrogen engines with zero CO₂ emissions that are ready for deployment in a very short time.
Result: Sustainable engine solutions with full performance and validated operational safety.
Does Felsaris also provide short-term support for CAD or CFD projects?
Yes, with our on-demand packages we can provide additional engineering capacities at short notice. Companies can flexibly decide whether they need support for just a few weeks or for several months. Since software license costs are already included, there are no additional fixed expenses. This ensures that even urgent projects can be implemented efficiently.
Result: Flexible capacities, fast results, full cost transparency.
What advantages do the CAD and CFD on-demand packages offer?
Our packages are tailored to meet the needs of startups, SMEs, and complex development projects. They differ in duration and scope, and offer benefits such as unlimited revisions, discounts on 3D printing services, and prioritized processing in the premium package. This gives customers predictable costs, flexible usage, and consistently high-quality results.
Result: Tailored support, predictable costs, and maximum efficiency.
What distinguishes Felsaris GmbH from large engineering providers?
Compared to major players in the industry, we work leaner, more agile, and significantly faster. With our approach, projects can often be completed up to 50% quicker, without compromising on precision or quality. Thanks to direct customer interaction and flexible workflows, we achieve shorter project timelines and deliver results tailored to the specific needs of our clients.
Result: Highest quality, consulting at eye level, and faster project execution.
