In a recent work, we optimized an airborne optical sensor, which is typically built into an impressive device for sensing data remotely, e.g. from helicopters. The mirror blanks for the optical sensor are made from glass ceramics with an extremely…

In our research project GAMMA we closely work together with MTU Friedrichshafen to optimize components of large turbochargers. Nicolas Lachenmaier, one of the leading aerodynamics engineers at MTU, uses CAESES® for the design of the turbine components. He provides a…

Intake ports are the final part of an engine’s air induction system. They connect the intake manifold with the combustion chamber and are opened and closed with the intake valves. This blog post gives you a short introduction of the relevant intake port design capabilities within CAESES®. In addition, a recent project is outlined where CAESES® and STAR-CCM+ were coupled to fully automate the shape optimization of an intake port.

A piston bowl is a recess in the piston crown primarily used in (direct injection) Diesel engines, where it basically forms the combustion chamber. The design and shape of the piston bowl influences the movement of air and fuel during…

For the fully-automated shape optimization with CFD, one key task is to robustly automate the geometry and mesh generation as well as the actual CFD flow analysis. Within one of our ongoing research projects, GAMMA, we recently had the challenge…

There is a lot of research going on to further improve the efficiency of ships by lowering the overall energy consumption. Besides the optimization of the operational profile of the ships (speed, trim, loading etc.), there are many things you…

Geometry scripting is really a cool thing! It allows you to create highly customized geometry parts – parts that are often impossible to create with the typical capabilities of a graphical user interface (GUI).

From time to time we receive NAPA IGES files from our maritime customers which are basically an assembly of often hundreds of single surface patches. The question is then: How can we quickly create a watertight, box-like flow domain for…

For the exchange of propeller geometry data, CAESES® offers the possibility to import and export files using a format that is called PFF (Propeller Free Format). We support the PFF format since these files are widely used by ship and…

Response surfaces, also known as surrogate models or meta models, are nowadays often used whenever the evaluation of a function is not directly possible or simply too expensive. In the context of engineering and simulation, a typical application is the…
