افتراضي PointWise 18.2 R1 build 2018-09-13


PointWise 18.2 build 2018-09-13
PointWise 18.2 R2 | 1.9 Gb
Pointwise has released a new, updated version of its computational fluid dynamics (CFD) mesh generation software. Building on experiences gained through participation in CFD workshops, this new release includes the ability to customize the near-wall mesh for accurate and efficient boundary layer resolution.


"High-order numerical schemes hold a great deal of promise for improving the accuracy of CFD with the added benefit of a decrease in the number of mesh cells versus linear mesh methods," said John Chawner, Pointwise's president. "Over the past several years we have been developing and testing new software to generate the high-order meshes needed by these new CFD solvers, and we are now able to release the first version of this capability."

"Mesh curving has been a research focus at PointWise for several years, partially funded by a NASA Phase I Small Business Innovation Research (SBIR) contract," said Dr. Steve Karman, the PointWise research engineer behind the new high-order capability. "Collaboration with several flow solver developers has been extremely helpful in evolving the technology to the level where realistic geometries with viscous boundary layers can now be curved. The initial release of this capability in V18.2 allows users to uniformly elevate their meshes to polynomial degree 2, 3 or 4. Under a follow-on NASA Phase II SBIR project the technology will be matured to permit mixed-order meshes and solution-based adapted meshes."

Pointwise has been fortunate to work with leading researchers across the globe while developing this high-order capability and is honored by their enthusiasm for its release in the production software.

Dr. Ryan S. Glasby of the University of Tennessee has been an evaluator of Pointwise's high-order meshes during pre-release testing. He wrote, "The release of PointWise 18.2 that includes polynomial degree elevation and mesh curving capabilities represents a watershed moment in the history of CFD. With this capability, CFD solutions generated by DoD HPCMP CREATE(TM)-AV Kestrel component COFFE with PointWise degree 2 meshes contained accurate coefficients of lift and drag with an order of magnitude fewer degrees of freedom than CFD solutions generated by other solvers on other meshes."

Dr. Peter Vincent, Reader in Aeronautics and EPSRC Fellow at Imperial College London wrote, "Compact high-order schemes can potentially offer industry a range of benefits including accurate and efficient resolution of unsteady turbulent flows. However, such schemes require high-order curved element meshes to work efficiently, and these have proven notoriously difficult to generate in a robust way, especially for complex geometries. I see the addition of such capability to PointWise as a potential game-changer in this regard, and I am confident it will enable adoption of compact high-order schemes amongst a wider community of fluid dynamicists."

Dr. Edwin Van Der Weide from the University of Twente had the following to say: "The new degree elevation and mesh curving capability in PointWise 18.2 enables us to generate high-order grids beyond the academic test cases we could handle with the SU2 in-house mesh deformation tools. As such, these new capabilities give us, and many other groups, the possibility to advance the development of SU2 to the level of industrially relevant configurations."

Dr. Z.J. Wang, Spahr professor of aerospace engineering at the University of Kansas and founder of hoCFD LLC, a software company offering a high-order CFD solver, wrote, "I am thrilled that PointWise is releasing a high-order meshing capability because it is considered the biggest bottleneck in high-order CFD simulations. This release is huge in propelling high-order CFD computations into mainstream real-world applications."

Pointwise Version 18.2 also accelerates the generation of surface meshes (named spacing constraints, a mesh spacing synchronization command, and a quick way to split curves into pieces of equal arclength), enhances the generation of hybrid meshes with the T-Rex technique, and offers improved user experiences (an on-screen tool for panning and rotating the view, a vastly expanded context menu, and a quick display of keyboard shortcuts).

About Pointwise. PointWise is the choice for CFD meshing, covering all aspects of preprocessing from geometry model import to flow solver export. Available for Windows, Linux, and Mac, you can generate structured, unstructured, and hybrid meshes including our T-Rex technique for highly-automated generation of boundary layer resolving hybrid meshes.

About Pointwise, Inc. Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today - reliably generating high-fidelity meshes. The company's PointWise software generates structured, unstructured, overset and hybrid meshes; interfaces with CFD solvers such as ANSYS FLUENT, STAR-CCM+, OpenFOAM, and SU2 as well as many neutral formats, such as CGNS; runs on Windows, Linux, and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Manufacturing firms and research organizations worldwide have relied on PointWise as their complete CFD preprocessing solution since 1994.
