When it comes to sediment simulations, the results of an analysis can heavily vary depending on which values you take for certain coefficients such as the Shield’s number. Often the default values of software solutions are not suited and need…
Video: Adjusting Displacement and LCB in 5 Minutes
In our latest CAESES® release 4.1.2, we have improved the methods to change existing geometries by means of shift transformations and shape deformations. In this context, existing geometries mainly means data that is given in another CAD system, and which…
SMM 2016 OSV Design Optimization Challenge
The world’s leading maritime trade fair SMM 2016 is currently taking place in Hamburg, Germany. This year, we decided to go there, and run a competition for the optimization of a ship hull design. We have picked a demo offshore…
Polycurve and Surface Splitting
The polycurve type in CAESES® is something that gets used quite a lot, in particular in the context of surface generation through the meta surface technology where you need to have a single curve definition. The polycurve simply takes a…
How to Create a Propeller Blade Tip
In our propeller design projects for maritime applications (i.e. ship and boat design), we use a special feature for creating the blade’s tip surface. This is a tricky region because there is a singularity, and as a designer you need…
Parametric Model of the TU Berlin TurboLab Stator
Efficient Geometry for TurboLab Stator Optimization Some time ago, we were asked whether we can provide a variable and robust CAD model for the TU Berlin TurboLab Stator test case. This stator is installed in a measurement rig at the…
Best Designs and Pareto Frontier
As some of our CAESES® users may already know, we really love to squeeze in small pieces of useful functionality into our maintenance releases. Why wait for a major release if our users can benefit from them right now? This…
Video: Parametric Skeg Modeling in 2 Minutes
Dear ship designers, In this blog post we want to demonstrate how fast the creation of a parametric skeg can be achieved in CAESES®. Given is a bare ship hull surface. This surface is then taken as the only input…
How to define boundaries in CAESES for ANSYS ICEM CFD
As most of you probably know, ICEM CFD is a popular meshing software from ANSYS. It is also one of the most used meshing software when we talk about our CAESES® customer base. ICEM CFD can be perfectly integrated in…
New Export Format for CONVERGE Users
Just a few weeks ago, one of our colleagues started a comprehensive optimization of an automotive engine component with CAESES®. More detailed, he had been investigating a piston bowl design. For the CFD analysis he used the simulation software CONVERGE…
