Our 2016 user group meeting, 21-22 September in Fort Worth will be the first chance to see our new release with unstructured hexahedra and more. There will also be technical presentations on future Pointwise development and a variety of user applications.
Chasing the Sun 3000 km across the Australian Outback is a challenge. And doing it in a solar powered vehicle is an even bigger challenge. But every two years the Stanford Solar Car Project, a student-run organization, arrives in Australia with a new design ready to take on the Bridgestone World Solar Challenge. This article summarizes the simulation driven design framework that enabled the team to analyze over 40 design iterations and improve the aerodynamic efficiency of their 2015 car, Arctan.
Finite-element methods for computational fluid dynamics simulations are increasing in popularity for many reasons, one of which is the relative ease with which more accurate solutions can be obtained. Degree elevation of a linear mesh is not usually a problem except for elements near highly curved geometric boundaries. This article describes a mesh curving method in three dimensions that uses an extension of an optimization-based mesh smoothing scheme to produce valid curved-edge, high-order meshes.
Pointwise provided a set of standard grids for workshop participants to use at this year's 3rd Propulsion Aerodynamics Workshop in Salt Lake City, Utah. These grids were created using several new features available in Pointwise's upcoming V18 release. An overview of some of these features and the workshop grids is provided. Some initial steady-state results for the S-Duct using these grids and NASA's FUN3D solver are presented.
Pointwise Version 18 is currently being prepared for production release. You have already seen some of its new features in the article “Unstructured Quad/Hex Meshes and Mesh Sizing Sources Coming to Pointwise” in the 2016 Q1 issue of The Connector. V18 also uses a new license manager called RLM, the Reprise License Manager. RLM has been tested by the Pointwise Advisory Team during V18's beta period and we believe it offers improved performance, robustness, and ease of use. More information on RLM will be available around the Pointwise V18 launch.
