Software for Simulation Engineers

Are you using CFD (Computational Fluid Dynamics) to design flow-exposed products or components? Is the fluid dynamic behavior of your design critical for realizing the performance requirements?

If your answer is yes, then CAESES® could be the perfect solution for you. CAESES® stands for “CAE system empowering simulation” and its ultimate goal is to enable engineers to design flow-optimal products. CAESES® gets used in various industries, typical areas of interest include ship hulls, turbomachines, ducts and manifolds, engine components, aerodynamic bodies, amongst others.

CAESES® comes with 3 components in a single & unified graphical user interface:


Upfront CAD

Create Robust Variable Geometry


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

  • Create more intelligent 3D geometries
  • Everything is geared towards the generation of design variants
  • Smarter shape controls to reduce degrees of freedom (hence save simulation time)
  • Simulation-ready and 100% robust, even for large sets of designs
  • One-time CFD-preprocessing work for all geometry variants
  • Examples: Blades, volutes, ducts, diffusers, pumps, engine components, wings, ship hulls

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 create a robust & smart parametric model for you, optionally including CFD automation. Everything gets documented and explained in detail. The setup is based on your wishes and requirements. It will be created in tight collaboration with you. Finally, depending on your situation, we can even wrap the entire model setup including optimization strategies into an easy-to-use interface for your daily work, so that no CAESES® expertise is required at all!


Note that we offer different licenses for companies and academic purposes. Ranging from a standard edition up to a power edition: There are several editions to choose from, depending on your application and design task. Read more ….


Free Student Pro License

We also offer a free academic pro edition for students! No limitations! Everything is in there: CAD, CFD integration and full optimization!

How to Get It

Simply request such a license directly from within CAESES® Free, via “menu > help > license upgrade > student license registration”. All we need is your certificate of enrollment (PDF) that you can submit when you upgrade your edition. As soon as your certificate expires, just send us an updated one using this email address, and we will extend it again.



You don’t have time or resources to learn a new piece of software? However, having a CFD-ready & variable model of your application in just a few days sounds great? Then simply get in touch with us. Together with your application-specific expertise, we can create a variable model for you that includes all your requirements, ideas and constraints. We can also assist you in setting up a fully automated design process on the basis of your existing tools and CAESES®. Read more …
