Meshing is always a compromise between computational efficiency and the needed accuracy. We need the smallest possible mesh to capture the effects that we consider as the most important in our simulations.
NUMECA-USA has worked closely with Masten Aerodynamics Lead, Allan Grosvenor, and his team to develop an HPC-driven workflow that enables concept development, evolution, and optimization, of vehicle configuration that takes into consideration aerodynamic performance, control, loads and aerothermal heating, with simultaneous trajectory optimization.
“We massively invested in NUMECA solutions more than 2 years ago, and are very satisfied with the level of precision they provide us.“ Dr.Takiguchi, Chief Engineer at Honda Automobile R&D Center.
Numerically simulated cavitating performance and open water performance of an SMP'15 propeller
This paper describes trends in CFD (computational fluid dynamics) techniques for simulation-based design and simulation-based operation.
The following case study provides an example of how HEXPRESS™/Hybrid can be used for treating unclean CAD and meshing it in less than a day for this kind of configuration.
As a key player in the aerospace market, at GKN Aerospace we need to be very demanding regarding the capabilities of the tools we use. In the fast-paced environment that is the CFD world, our engineers need a robust and quick mesh generator, providing an accurate capturing of our complex turbomachinery geometries.
Computation referring to the towing tank tests performed by MOERI on the KCS.
The paper describes progress in software and business solutions for advanced CFD applications.
An innovative computational approach, integrating mesh generation, CFD simultaneous analysis of noise source and propagation, with acoustic radiation, is presented and applied to the simulation of the Advanced Noise Control Fan (ANCF) developed by NASA Glenn Research Center.
