Isogeometric Research Wins Award
Research on isogeometric analysis won the 6th John Argyris Award for best paper by a young researcher at the 10th World Congress on Computational Mechanics. Dominik Schillinger, who conducted his research at the Institute for Computational Engineering and Sciences (ICES) at the University of Texas at Austin, won for his paper titled An Isogeometric Design-through-analysis Methodology based on Adaptive Hierarchical Refinement of NURBS, Immersed Boundary Methods, and T-spline CAD Surfaces.
Isogeometric methods allows FEA and other computational techniques to work directly with the CAD geometry, bypassing mesh generation entirely. [No meshing? Where’s the fun in that?]

Super Linear Parallel Scalability with Cobalt CFD
Cobalt Solutions, developers of the Cobalt CFD code, issued a news release backed up by a technical paper in which they cite high scalability of their CFD solver on tens of thousands of processors with similar potential for hundreds of thousands of processors.
The paper, Can Legacy Codes Scale on Tens of Thousands of PEs or Do We Need to Reinvent the Wheel?, includes data showing Cobalt’s super-linear scalability all the way up to 21,856 PEs (processing elements) for a grid of 49 million cells.

[It will be interesting to see where this leads. Is it some sort of “gloves come off” moment? I’ve seen the “we must start from scratch” argument fail before.]

How to Photograph Fluid Flow
I am a terrible photographer and beyond help. But others of you may benefit from this article on How to Shoot Liquid Flow Photographs.
I really enjoyed the book by professor Hughes et. al (http://amzn.com/0470748737). I have been planning to write a small Isogeometric c++ program since I read the book, I need to learn more about nurbs. But, John, you are correct, where is the fun if meshing is not involved???
Cesar: NURBS are fun too. I learned by starting with Mortenson’s book, then Farin, and Piegl & Tiller.
I’m planning to buy the The NURBS Book (http://amzn.com/3540615458). I have a list about 15 books in my wishlist, topics goes from optimization, NURBS, C++,C##, SQL, git, etc… all the topics I think I need to create a simple yet robust CAE related program. Thanks for the recomendation!
