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. With CAESES® as the Upfront CAE workhorse in the pre-CAD stage, simulation engineers from any industry can explore a multitude of design variants within highly automated workflows. Traditional CAD systems in the market are not designed to create geometry for analysis and it is difficult to vary complex shapes automatically. From the start, our modeling capabilities were specifically developed for simulation, especially CFD.

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

  • Upfront CAD: Powerful 3D modeling for the pre-CAD stage
  • Upfront CFD: Smooth integration of simulation tools
  • Upfront Optimization: Easy design explorations and shape optimization



Upfront CAD

Powerful 3D Modeling in the pre-CAD Stage

Parametric 3D Modeling

CAESES® is a comprehensive Upfront CAD tool:

  • Create smarter parametric geometries from scratch
  • Focus on variable and simulation-ready geometries
  • One-time CFD-preprocessing work for all geometry variants
  • Import and deform existing geometries
  • Examples: Blades, volutes, ducts, diffusers, engine components, wings, ship hulls

Utilize CAESES® as your primary CAD tool, or use it as an Upfront CAD tool in a collaborative and integrated way with your traditional design and production CAD.
