CAESES

CAESES

CAESES® is a flexible CAD platform for fast and comprehensive design studies with simulation tools. Integrated capabilities for CFD automation and shape optimization make it an all-in-one design tool for simulation engineers.

 

CAESES vs. Traditional CAD Tools

CAESES® stands for “CAE System Empowering Simulation” and its ultimate goal to design optimal flow-exposed products.  It’s literally made for simulation experts, but also a great choice for CAD engineers – especially if they work closely with the simulation department.

CAESES® focuses on automation – that’s the main difference when you compare it to traditional CAD tools. The geometry generation can be fully automated (to create new design candidates) and is 100% robust. This is essential for running design studies with simulation tools, e.g. on HPC clusters. At the same time, you can build design constraints into your CAESES® model, such as cross-section areas, minimum distances to keep, hard points, etc.

  • Simulation-ready: CAESES® geometries are closed, clean and can be meshed without any pre-processing
  • Robust during variation: No broken or infeasible designs during an automated geometry generation process
  • Fixed Identifiers: Patches and surfaces keep their identifiers (names, colors) in automated meshing processes
  • Parameter reduction: Fewer design variables, leading to tremendous computational time savings
Robust, efficient variable geometry for simulation studies

Explore and Find Optimal Designs Much Faster

CAESES® also contains capabilities for automation of simulation tools to couple flow and structural analysis, and integrated strategies for parameter studies and advanced optimization. Together with the variable CAESES® geometry, this allows you to efficiently investigate large sets of new design candidates with your simulation package of choice!

CAESES® itself contains no CFD or other simulation methods, instead it seamlessly integrates your existing tools to create a closed loop.

 

Typical Applications

CAESES®  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.

 

Your Advantage: Available for Linux

Having CAE tools that can be automated on HPC clusters is crucial nowadays! That’s the reason why we also support Linux platforms and a batch mode (non-GUI version), to let you exploit all your hardware resources. Of course, we also support Windows systems. Read more.

A Short Comparison to Other Tools

CAESES® in 30 Seconds

One of the founders from FRIENDHIP SYSTEMS gives you simple answers to the question what CAESES® does: Read the short interview …

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 or other simulation 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.

Simulation Packages

CAESES® does not contain any CFD or simulation capabilities. Instead it seamlessly integrates existing simulation 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.
