Application By John Rhoads, Ph.D.
Senior Engineer, Pointwise

Computational fluid dynamics (CFD) is essentially a series of approximations; the role of the practitioner is managing the magnitude of the errors in these approximations. In CFD, one of the most basic approximations lies in the type of cells used for the simulation. This article will address some of the potential pitfalls encountered with a generic cell-centered finite volume scheme.

Application By Alp Emre Öngüt, M.Sc. and Dipl.–Ing. Norbert Hosters
Chair for Computational Analysis of Technical Systems (CATS)
Center for Computational Engineering Science
RWTH Aachen University, Germany

At the Chair for Computational Analysis for Technical Systems (CATS) at the RWTH Aachen University, Pointwise is used as the mesh generation tool for various computational fluid dynamics (CFD) applications, such as design and optimization of profile extrusion dies, simulation of blood pumps, fluid structure interaction for colloidal aggregates and aeroelastic simulation of horizontal axis wind turbines. In this article, mesh generation with Pointwise for the wind turbine application is explained.

Practical Shape Optimization using CFD
Posted Tue December 09, 2014 @11:03AM
Print version Email story Tweet story
News Today’s engineering firms have embraced optimization as a critical component within simulation-driven design. Although the algorithms are reasonably mature and well understood, the different methods for the shape variation of critical surfaces and components are not.

The free FRIENDSHIP SYSTEMS whitepaper gives a comprehensive overview of the various methods available today and their relative strengths and weaknesses for conducting practical shape optimization using CFD.
