![]() ![]() The following screenshot shows a typical vda-file, which was our starting point: The goal was to take this ASCII file and offer a fast and robust one-click solution in CAESES ® to generate a solid body from this point data. However, this step-by-step approach took them roughly 30 minutes for each design. The status quo had been that they already tried to semi-automate this process in a traditional CAD software. ![]() What they needed now was a very quick, single-click solution to create a solid body from this ASCII file, in order to conduct structural analysis for the impeller. In NUMECA Autoblade, such a model can then be exported using an ASCII format (*.vda), which basically contains point data for the meridional hub and shroud contours and the blade geometry. Some of their impeller designs were created by applying NUMECA software. ![]() They design large turbochargers for diesel engines, and they use CAESES ® for the design of volutes and other engine components. Some time ago, our customer MTU Friedrichshafen (the core entity of Rolls-Royce Power-Systems) approached us with a very interesting request.
