Simulation-Ready

Simulation-Ready Geometry

Geometry in CAESES® is ready for automated meshing with external tools. All models can be set up with fixed patch identifiers such as colors that get passed over to your simulation tools. These identifiers do not change during variation, which allows you to re-use and automate the meshing and analysis procedure for new design candidates.

Create a clean and robust 3D geometry including boundary information for CFD.

Save Time by Automation

Derive robust parametric geometries for the flow and solid domains of your model as an input for your meshing and simulation software. With these support geometries, automate the CFD analysis and – if given – the structural analysis by putting everything into a single loop. These high automation possibilities can give you a massive speed-up in the early phases of a design process and save you weeks and months of time!

By using CAESES®, we could massively bring down our turbine design cycle from several months to only a few weeks.

Closed Surface Triangulation

In addition, the generated geometries in CAESES® are typically watertight i.e. closed and absolutely clean. You will have no issues with overlapping surfaces or gaps. However, if needed, you can apply healing and snapping mechanisms to fix a surface triangulation. This issue is critical if your meshing software is using STL input. The coloring mechanisms are also available for sending information about the different surface patches to your meshing setup. Check out this short tutorial video about watertight meshes.

More Information

There is an article about the “colored” IGES and STEP format of CAESES® that is of interest for several simulation packages such as STAR-CCM+. Another blog post “New export for CONVERGE users” gives information about coloring surface patches for robust and easy data exchange with CONVERGE CFD.
