3D Geometry Modeling and Variation for CFD EngineersCAESES is software that focuses on the optimal design of complex 3D surfaces. It allows you to create variable & simulation-ready geometry that is robust during variation. Perfectly suited for automated design explorations in CFD departments.

Flow Optimization

CAESES® helps engineers to design products with optimal flow characteristics. It lets you build variable and simulation-ready geometry that is 100% robust during variation. CAESES® also automates your simulation runs to conduct design studies and shape optimizations.

Take a Tour!

CAESES®' foundation is a powerful and flexible 3D parametric modeler. From the start, our modeling capabilities were specifically developed for automation and simulation, especially CFD.


CAESES® is an integration platform that can launch and control the CFD (or other) simulation studies. Any CFD code that can be run in batch mode from a geometry file and input script can be coupled.


Vary and Explore! With CAESES®, there is no need for a separate optimization software. CAESES® contains many inbuilt strategies for design explorations and shape optimization.

Easy-to-use template models that include CFD and optimization


No time to learn a new software? No problem!
We provide variable and robust geometry models that are customized and easy to use for automated design studies – integrated into your workflow, and connected to your meshing and CFD tools! You need no CAESES® expertise for this, your wrapped template come with an intuitive user interface.

Before introducing CAESES we ran about one hundred RANSE simulations per year. On the basis of CAESES we are now able to undertake several ten thousands of viscous simulations every year with no additional effort. This gives us an exceptional insight for key product decisions that we would not be able to generate without CAESES.

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.
