Why CAESES?

CAESES® stands for “CAE System Empowering Simulation” and its ultimate goal is to design optimal flow-exposed products. It focuses heavily on simulation engineers that need automation, in particular in the context of geometry generation. 

CAESES® focuses on automation!

With a focus on automation, CAESES helps you to be more productive and to drive more value from your existing simulation software investments. Your product development benefits from a massive acceleration, while fostering design exploration and innovation.

Automation-Ready

As a central component of CAESES, the creation of complex geometry variants is automated and 100% robust, thanks to the dependency-based modeling approach – as opposed to the history-based approach of other CAD systems. The entire process can be optionally scripted to run in batch mode.

All generated geometries are clean and watertight without any manual pre-processing, which saves you hours of work. CAESES models contain fixed patch identifiers (surface IDs) to automate the meshing process.

CAESES individual colors

Assign identifiers, colors and triangulation settings for each individual surface patch which will be preserved for all generated designs

 

Efficient Geometry

CAESES® models have less parameters which saves computational time in optimization processes. You can even build design constraints into your CAESES® models, such as cross-sectional areas, minimum distances to keep, manufacturing constraints, hard points, etc. This ensures that only valid designs are created during optimization runs. No more waste of time due to infeasible designs!

Find Optimal Designs 

CAESES® itself contains no CFD or other simulation methods, instead it seamlessly integrates your existing tools to create a closed loop. The capabilities for automation of simulation tools let you plug in flow and structural analysis.

In addition, CAESES® comes with integrated strategies for parameter studies and shape optimization. Together with the geometry modeling, you have everything you need to investigate large sets of design candidates in a massively reduced time frame.

CAESES can also be used in combination with existing optimization tools, such as Dakota, OptiSLang, Optimus, ModeFrontier etc. In these situations, CAESES runs in the background as efficient and robust geometry engine.

FAQs

 

What makes CAESES® unique?

CAESES® is exclusively made for automated design processes in the CAE industry. Hence, the CAD capabilities focus on maximum robustness, fixed patch identifiers for automating the meshing, triangulation controls, scripting possibilities for highly customized models and much more in this context. The goal is always to robustly generate feasible design candidates in an automated way. The geometry creation does not break or fail to regenerate, for which a unique dependency-based framework is implemented.

 

I have a CAD tool already, so why CAESES®?

CAESES® is typically used as an upfront CAD tool in a collaborative and integrated way with traditional design and production CAD (e.g. CATIA, NX, Pro/E, SolidWorks). These traditional tools, although powerful, are detail-oriented and encompass features and capabilities, which may not be relevant for simulation.

 

Who is your target user?

CAESES® targets simulation engineers that need a flexible tool for the pre-CAD stage, to explore novel and innovative designs in an automated process. There is a strong focus on CFD engineers, but CAESES® is also coupled to structural analysis. Since CAESES® has a powerful CAD kernel, it can be a flexible solution for CAD engineers that need a high robustness, advanced scripting and automation capabilities.

 

Is it an optimization software?

Yes. CAESES® provides a set of strategies for advanced parameter studies and shape optimization (e.g. response surface techniques) that can be readily triggered and which are integrated in the GUI. If you already use an optimization software in your company, you can integrate CAESES® as a geometry engine into your existing loop. CAESES® has a batch mode and can be controlled by other optimization software, it is absolutely simple and robust. We have various optimization and CAE partners, where we make sure that our solutions work together as easy as possible for the user. Note that CAESES® is a geometry modeler in the first stage. The CAD capabilities are the key difference compared to other general-purpose optimization software. Even though the geometry in CAESES® can be connected to the integrated optimization strategies, it is an optional offer that you can use.

 

Does it also contain CFD solvers?

No. CAESES® does not contain any CFD or simulation capabilities. Instead it seamlessly integrates existing simulation tools that can be triggered in batch mode.

 

How can I license it?

We provide different licenses for companies and for academic purposes. Ranging from a standard edition up to a power edition: There are a few editions to choose from, depending on your industry, application, design task and budget. We are also open to discuss special packages for small companies, start-ups and freelancers. Contact us or browse here for more information …
