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…
How To Create a Response Surface in 4 Easy Steps
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…
