Short video about how to create a closed and colored flow domain for ship hull geometries. As a starting point, IGES files from NAPA or other CAE/CAD systems are imported. By means of healing and Boolean Operations, the box-like flow domain gets created in a fully-automated way. It can then be readily meshed by grid generation tools. More information can be found in the corresponding blog post.

CAESES® is a great tool for intelligent design of volutes for pumps and turbochargers. This video gives an introduction to modeling the main surface of a volute. In order to keep it easy, the cross section is a simple circle for which the area can be controlled in circumferential direction. CAESES® comes with a set of example volutes which are more complex. If you interested in creating your own model, don’t hesitate to get in touch with us. We can support you so that you have your model ready in just a few days.
Axial Fan Optimization
Check out this nice video which shows the entire process of parametric fan modeling, CFD integration and automation using STAR-CCM+, as well as CFD postprocessing in CAESES®:
With version 4.0, CAESES® integrates smoothly with Dakota, the free optimization toolkit from Sandia Labs.
Free Form Deformations on a Fuel Injector
With version 4.0, CAESES® offers free form deformations (box deformations) to allow users to quickly and easy modify existing geometries (e.g. imported ones). These capabilities greatly complement the parametric CAD functionality of CAESES® so that for each situation there is the right method available to conduct shape studies and optimizations.
Free Form Deformation Tutorial
This is a short video that shows the basic process of how to set up a free form deformation in CAESES®. First, a simple duct is imported using STL data. In the next step, a bspline box and a free form deformation are created and configured so that the initial “dead” shape can now be squeezed and pulled.

This is a step-by-step video that was derived from a blog post. It shows the geometry creation of an simple automotive component where pattern-based structures are set up using solids (breps) and boolean operations.
Skeg Modeling for a Ship Hull in 2 Minutes
This is a very short video that shows how a skeg model can be created in CAESES® and how it is automatically attached to a bare ship hull.
This is a rather old video but still gives you a first idea of what is CAESES® all about. Note that we had two re-branding phases within the last years, which is the reason that some videos still show the former product names (“CAESES / FFW” and “FRIENDSHIP-Framework”). Today, it’s simply called CAESES®. The upfront CAE-software CAESES® and its free version CAESES® Free focus on the simulation-driven design of flow-exposed products. Main features are parametric 3D modeling, tight CFD integration and automated shape control for systematic studies and formal optimizations.
Axial fans and other rotating geometries can be easily parameterized in CAESES®. This video gives you a short demonstration of a parametric fan model, along with an automated pitch variation of the blade. The geometry model is specialized for automated processes and can be directly utilized in CFD-based optimizations using commercial or non-commercial CFD packages. CAESES® is generalized software for parametric design and optimization of any complex geometry with flow-related tasks. In particular, there are dedicated methods for turbine and compressor blades as well as for maritime propeller design.
Blade Design with Meridional Camber Curve
This video demonstrates the new capabilities of version 3.1 using the meridional camber curve for impeller design. This curve is mostly used for pump design.
Centrifugal Impeller Design
CAESES® provide everything that is needed for blade design, in particular in the context of simulation-driven design. In this video, an example of a centrifugal compressor is shown. The model was built from scratch and can be controlled by typical blade parameters. Everything can be fully customized, i.e. this is not a black box model – there are no restrictions to the profile shapes etc! This example is shipped with the software and can be found in the documentation browser.
Design and optimize axial blades such as turbine and compressor blades. This video gives a brief overview about the design steps. The stream section curve type is focused; it does the job of mapping a 2D profile into the 3D space, while taking into account meridional curves and stacking axis. The parametric model in this video is part of the samples section in CAESES®.
Note that the video shows a bit more (e.g. some profile checks) than you actually need for a blade design. To boil it down, in the end you only need a feature definition with a stream section. Create a curve engine and connect your stream section definition with the radial distributions for your profile parameters. Create a meta surface based on this engine. That’s it. Maybe 20-30 minutes of work if you already have a 2D profile description.
The stream section itself can cope with angle- (m’,theta) and length- (m,r*theta) preserving profile definitions. With version 4.0, we also support the system (z,r*theta).
This video gives a brief introduction to propeller design in CAESES®. The so-called generic blade and cylinder transformation are provided for design of fully-parametric maritime and non-maritime propeller blades including parametric profile design and user-defined rake, skew and pitch distributions. Multiple profile types within one blade via blending functions are possible. Ready-to-use NACA profiles can be directly used. Set up your own mathematical formula and geometric curve definitions of profiles, mean camber and thickness distributions. There is a 2D drawing functionality available for propellers and a PFF-Import/Export (Propeller Free Format). Furthermore, blade analysis of imported surface geometry is provided, e.g. for reconstruction of parametric models.
In this video selected parameters of a ship hull are changed in order to modify the shape. The model was set up from scratch and is included in CAESES®. It can be used as is or might serve as a starting point for your own individual parametric model of a container vessel. The software comes with a set of different ship types, e.g. yachts, tanker, bulker and supply vessels as well as functionality for parametric design of maritime propeller blades.
Starting with version 3.0 of CAESES®, it is now easier to connect any simulation tool to the GUI. This video shows the single steps of the STAR-CCM+ coupling process. As a prerequisite, a STAR-CCM+ setup (sim file) is assumed to be given along with a set of JAVA macros. These files are then used for utilizing STAR-CCM+ in batch mode. As an example, a parametric s-duct geometry is modified and analyzed by STAR-CCM+. Finally, some of the post-processing capabilities of CAESES® are shown.
This video gives a brief overview of the connection to XFlow.
Automated Variation of Geometry
In this short video tutorial design variants are created from a parametric baseline model. For demonstration purposes, a simple wing design is utilized that has been created before in CAESES®. These models and their variants can be directly coupled to commercial and non-commercial CFD-packages.
Introduction to Feature Definitions
This is a short introduction to Feature Definitions (FD) in CAESES®. With FDs, you can fully customize the software to your needs by encapsulating command sequences and by writing your own macros. Examples are custom curve types, proprietary import and export formats, functions etc. This video helps beginners to get familiar with the basics of this powerful functionality. Really a recommendation!!!
The design viewer is a CAESES® widget that allows you to compare your generated design variants in a single window. The design variable values are listed along with constraints and objective values. Screenshots of the geometry and flow results as well as an interactive 3D geometry are available for detailed assessement. Here is a very short video that shows the design viewer:
