CAESES® stands for “CAE System Empowering Simulation” and its ultimate goal is to help engineers to design leading flow-exposed products. CAESES® is a unique optimization environment that offers integrated simulation-ready CAD capabilities, full CFD automation and state-of-the-art optimization strategies. All in a single and unified user interface.

  • Build variable & simulation-ready geometry that is 100% robust during variation
  • Automate your meshing and simulation runs
  • Conduct design studies and shape optimizations

CAESES® gets used in various industries, typical areas of interest include ship hulls, turbomachines, ducts and manifolds, engine components, aerodynamic bodies, amongst others.




How to create a smart and 100% robust design variant of a product? For this purpose, utilize CAESES® as your primary CAD software to create variable and simulation-ready geometry, or use it in a collaborative and integrated way with your traditional design and production CAD.

How To Buy

If you are interested in buying a commercial pro license of CAESES®, then just get in touch with us directly. We’d happy to discuss your individual application and how CAESES® could fit into your current design workflow.




Pilot Project

Typically, we run a pilot project with you together in the first stage, to make sure you have a good and effective start with CAESES®. In such a project, we can create a robust & smart parametric model for you, optionally including CFD automation. Everything gets documented and explained in detail, to make you able to apply changes to the setup in the future. The parametric model can be based on all your wishes and requirements. It is created in tight collaboration with you. Depending on your situation, we can even wrap the variable model setup including CFD automation and optimization into an easy-to-use interface for your daily work, so that no CAESES® expertise is required from your side.


We offer various fast services on the basis of CAESES® for specific CFD-based design tasks and workflow bottlenecks. Check out our services page for more information.

“We launched a pilot project with FRIENDSHIP SYSTEMS to evaluate CAESES® in May, it helped us solve a time-critical task in July and it became a design tool by October. By then we had created flexible and robust parametric models for complex parts, enabling us to optimize in design spaces we had previously not been able to explore.”

A Short Comparison to Other Tools

When it comes to the CAD modeling capabilities, CAESES® has its focus primarily on the design and variation of complex free-form surfaces. We target CFD engineers that need a handy and flexible tool for the pre-CAD stage, to explore new and innovative designs, and to give recommendations to the CAD engineer.

Our users build models that typically have less parameters than traditional CAD models, and they skip details that are not relevant for simulation. Instead, they build-in parameters that follow a flow-centric thinking, to have an intuitive and effective control that is related to the flow. Furthermore, our users often set up a model such that the patch names and edges are fixed during a variation, in order to be able to fully automate the meshing procedure. As a result, creating and analyzing a new design candidate of a geometry is absolutely robust. The robust variation of parametric geometry models is really the core competency of CAESES®.

In terms of optimization, CAESES® offers a set of strategies for advanced parameter studies and shape optimization. Here, our focus are CAE engineers that need to automatically vary a geometry model. Furthermore, CAESES® has a batch mode possibility and hence can be controlled by other optimization software. So if you already have an optimization software, you could simply stick to it and use CAESES® only for the robust and efficient generation of geometry variants. This is one typical situation in our user base.

As a final remark, CAESES® is completely independent of the meshing and simulation software that you use in your company. We are not restricted to a specific vendor, which is of interest for our users when they consider to jump on another simulation software, for instance.
