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® (formerly known as FRIENDSHIP-Framework) could be the perfect solution for you.


CAESES® stands for “CAE system empowering simulation” and its ultimate goal is to enable engineers to design optimal products.

Traditional CAD systems in the market are not designed to create geometry for analysis and it is difficult to vary complex shapes automatically. With CAESES® in the pre-CAD stage, simulation engineers from any industry can explore a multitude of design variants. From the start, our modeling capabilities were specifically developed for simulation, especially CFD. Engineers can save weeks and months by using CAESES® in their simulation department!

So what’s in there? CAESES® comes with 3 components in a single & unified graphical user interface:

Create Variable Geometry

How to create a smart 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, focusing the creation of design variants
  • Smarter shape controls to reduce degrees of freedom (hence save simulation time)
  • Simulation-ready and 100% robust
  • One-time CFD-preprocessing work for all geometry variants
  • Import and deform existing geometries
  • Examples: Blades, volutes, ducts, diffusers, pumps, engine components, wings, ship hulls

Upfront CFD

Connect all Your Tools

Connect your CFD package in just a few minutes to the environment of CAESES® to analyze a new design variant with a single click. CAESES® integrates with most of the leading commercial CFD codes as well as in-house codes.

Examples for simulation tools that have been coupled to CAESES® are STAR-CCM+, ANSYS Fluent/CFX, NUMECA products, OpenFOAM, SHIPFLOW, to name a few.

Free Student Pro License

You might think we are crazy, but … we also offer a free academic pro edition for students! No limitations! Everything is in there: CAD, CFD integration and full optimization! 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. Isn’t that great?


Professional Quick Start

Do you want to conduct highly automated design studies and shape optimizations with CAESES®? And do you want to get fully productive with it in shortest time?

Then simply ask us to set up a variable and robust CFD-ready model for you. Quick and professional. We create tailored parametric models for you in just a couple of days, based on your requirements and constraints. We assist you in integrating it in your existing workflow. With this, you can immediately benefit from your intelligent model, to run 100% robust shape optimizations with your simulation tools.

Automation of the Design Process

We can also support you to fully automate your design process on the basis of CAESES®. This includes:

  • Automatic fitting of “dead” geometries into intelligent and variable geometries
  • Coupling of several simulation and meshing tools in a single GUI
  • Automation of the full CFD and optimization process (import geometry > fitting > single-click design studies & optimization > assessment)

Don’t hesitate, just fill out the contact form and we will get back to you today! Together we thoroughly discuss all the details and requirements of your application. As a positive side effect, we also get to know each other so that you have a good picture of the friendly and supportive team behind CAESES®.
