CAESES® stands for “CAE System Empowering Simulation” and its ultimate goal is to help engineers to design optimal flow-exposed products.

CAESES® gives you innovative CAD capabilities to create variable geometry models that are geared towards simulation. These models are perfectly suited for fully-automated workflows, such as parameter studies and shape optimizations with CFD (Computational Fluid Dynamics).

The geometry that is created in CAESES® gives you 3 major benefits:

  • Simulation-ready: CAESES® geometries are closed and can be meshed without any pre-processing
  • Robust during variation: No broken or infeasible designs during an automated geometry generation process
  • Parameter reduction: Fewer design variables, leading to tremendous computational time savings

CAESES

In addition to specialized CAD, CAESES® contains easy-to-use capabilities for automation of simulation tools (or any other external tool), plus fully-integrated optimization strategies. All you need to set up your own CFD-driven design process, and to efficiently investigate large sets of new design candidates.

With this, CAESES®  is not just some specialized tool – it is your comprehensive platform for highly customized CAD models, CFD automation and shape optimization – all in a single and unified user interface!

  • Build variable & simulation-ready geometry that is 100% robust during variation
  • Automate your meshing and simulation tools
  • Conduct design explorations and shape optimizations with integrated strategies

CAESES® itself contains no CFD methods, instead it seamlessly integrates existing CFD tools to create a closed loop. It is used in various industries, typical areas of interest include ship hulls, turbomachines, ducts and manifolds, engine components, aerodynamic bodies, amongst others. CAESES® is suited for both internal and external flow applications, and it is available for Windows and Linux. Check out all details below.

Optimization with Adjoint CFD

The use of adjoint CFD methods has been getting more popular in recent years. As an answer to this, CAESES® allows you to couple the results of adjoint CFD with the geometry parameters of your model. With this, you can bring down the number of considered parameters and run faster shape optimizations.

CAD Modeling

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 lightweight and flexible tool for the pre-CAD stage, to explore novel designs, and to be able to finally hand over an optimized/improved geometry to the CAD department.

Our users build models that typically have fewer 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 efficient control that is related to the flow. Furthermore, our users set up models 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 perfectly robust. The robust variation of parametric geometry models is really the core competence of CAESES®.

Optimization

CAESES® gives you geometry modeling in the first stage! This is a key difference to other general-purpose optimization software. Besides that, CAESES® also offers a set of strategies for advanced parameter studies and shape optimization that can be readily used. Our focus are CAE engineers that want to automatically vary a CAESES® 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. We have various optimization partners where we make sure that our solutions work together as easy as possible for the user.

CFD Packages

CAESES® does not contain any CFD capabilities. Instead it seamlessly integrates existing CFD tools that can be triggered in batch mode. Finally, 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 might be of interest when you consider to jump on another simulation software or if you want to use in-house tools.
