Upfront Optimization

Upfront Optimization

With CAESES®, there is no need for a separate optimization software. CAESES® contains many sophisticated optimization algorithms ranging from single-objective strategies for fast and efficient studies, to more complex multi-objective techniques which are effective at conducting a global search of a highly non-linear design space containing many local minima and maxima.

Design Studies and OptimizationWhy is it in there? CAESES®‘ parametric models and its free form deformations are ideally suited for the automatic generation of design variants. Once the models are set up with smart parameters or functions of parameters, they can be varied in a number of different ways. You can configure a CAESES® design engine (algorithm) to automatically vary the parameters within the set bounds in a user-specified manner. The engine will systematically investigate the design space by linking to CFD to carry out the simulation studies.


Optimization Capabilities

With CAESES®, you are equipped with state-of-the-art optimization functionality. The following capabilities are included and can be readily used:

  • Parameter studies and sensitivity analysis
  • Single- and multi-objective optimization algorithms (constrained/unconstrained)

Variant Management
Easily step through the different designs to look at the CFD results and the geometries, CAESES® manages the entire data for you and makes design studies incredibly easy!

Email Notifications and Push Messages
You are not in the office and you want to know the status of your current optimization run? Then you will enjoy our convenient notifications that can be automatically sent by CAESES®‘ design engines to your mobile phone!

Variant Assessment and Post-Processing

CAESES® gives you everything you need to understand your study, and to pick the optimal design candidates. This makes CAESES® much more than a simple optimization platform, it is your great and unified tool for variant assessment and data visualization:

  • CAESES® includes its own interactive 3D post-processing environment! Understand overall performance characteristics (e.g. resistance, pressure loss, lift coefficient, flow rates) or look at the details of the flow patterns (e.g. cut plots, surface plots, trajectories).
  • Create 2D/3D charts incl. correlations to find the most important design variables of your task
  • Browse result tables to sort your designs based on objectives, constraints and variable values
  • Create your custom PDF reports, and include e.g. your company logo in these reports
  • Compare all generated geometries and corresponding simulation results side-by-side in the amazing design viewer!

Dakota Interface

Are you using the free optimization toolkit Dakota (from Sandia National Labs) in your department, or you want to introduce it? CAESES® interfaces smoothly with Dakota so that the full method set of Dakota can be applied directly within the CAESES® GUI! There is no additional Dakota installation required – everything comes with CAESES® and is ready-to-go… This is really a great symbiosis!

Batch Mode

Do you already use another optimization tool in your company, and you want to stick to it instead of using the inbuilt algorithms? No problem! For this common situation, you can run CAESES® in its super-easy batch mode as your powerful CAD engine, i.e. to exclusively generate geometry variants – driven by your optimization software of choice. If required, everything in CAESES® can be scripted, using a very intuitive and easy-to-learn command language. Really powerful!


Your Benefits

Understand the effects and impacts of design changes! For complex products, this is not always obvious. CAESES®‘ optimization component helps you to easily dig into the design task to find the best design candidates during your study. Save time and also CFD license costs by using e.g. correlations (to reduce the number of design variables) and smart optimization strategies such as response surfaces etc.

And not to forget: Save plenty of time by learning and using only a single tool, CAESES®. CAD modeling, CFD automation and finally optimization – everything in a unified single GUI! No hassle with error-prone scripting of complex tool chains, CAESES® users can really focus on their design task. This is highly effective – give it a try!
