Ship Hull Design
Design ships with better flows! CAESES® allows you to build robust parametric ship models with smarter shape control. It is the leading software solution for naval architects that are interested in CFD-based hull optimization – to create better flows around their designed vessels.
The focus with CAESES® is on the underwater part of the ship:
Create a variable hull model, connect your CFD and run studies. Finally pick an optimized hull shape that outperforms similar ships in the market.
Create Smarter Variable Models from Scratch
Set up a smart variable geometry while at the same time you build-in all your design constraints (displacement, center of buoyancy, hard points etc.). Save time by only generating feasible designs – manually or fully automated by using the intuitive variant management system of CAESES®.
Fast Optimization of Existing Ship Hulls
If your time frame is short and you have no time for creating a whole model, you can use the efficient Lackenby shift transformations and other deformation methods of CAESES®. These transformations allow you to intuitively reshape your hull, again manually or automated in an optimization. Works with any imported geometry!
In an easy-to-use and intuitive way, CAESES® provides you the most important hydrostatic quantities such as displacement and moments of inertia etc. These values can be calculated manually for a new design, or fully automated for a set of design candidates.
Leverage your Flow Analysis Tools
CAESES® closely integrates with your CFD and CAE analysis tools – no matter which CAE package you use. There is also an add-on for the CFD code SHIPFLOW, the industry standard for shipbuilding. Connect typical analyses to your CAESES® model such as ship hull hydrodynamics, wave resistance, and wakefield analyses, involve motion analyses of vessels and platforms with seakeeping codes, as well as propeller performance with CFD.
As a new development (still in a beta phase), CAESES® hull design setups can be fully wrapped into an easy-to-use interface, including meshing, CFD analysis and even optimization runs. Based on the tools that you use in your company. Just change the hull’s main dimensions and other project-specific key parameters and let CAESES® do the number-crunching job of finding the optimal design candidate. Here is a short video that demonstrates how templates can be used from within a browser (see also the blog post about the SMM competition).
CAESES® allows you to define any type of 2D section for marine propeller blades. For example, point data can be automatically imported and interpolated or parameterized, and complex Excel sheets can be accessed or even completely transferred to the CAESES® environment. CAESES® comes with a set of NACA profiles, but sections can also be defined by yourself using the CAESES® feature programming language. There are also complete parametric propeller setups based on standard series (e.g. Wageningen – see this blog post). CAESES® gives you everything you need to model typical marine propellers and special types such as surface-piercing or racing propellers, high-skew propellers, ducted propellers and submarine propellers. The propeller add-on gets used by large companies such as ThyssenKrupp Marine Systems and Caterpillar.
