This Week in CFD

Software Patents

In a closely watched ruling (maybe only by us software people) the U.S. Supreme court ruled unanimously in Alice Corp. v. CLS Bank that you can’t get a software patent for an abstract idea for the reason that it is simply a building block of human ingenuity. In other words, it doesn’t pass even the first test for patentability let alone those of novelty, obviousness, and vagueness.

This ruling does not imply an end to software patents, only that they must be more substantial than an idea that could be computerized and would actually need to demonstrate improvement to some actual function (i.e. actually be implemented).

Another interesting tangent on this ruling is that Alice Corp. is regarded as a “non-practicing entity” i.e. a patent troll.

Events and Business

  • CD-adapco announced a partnership with researchers at the Univ. of Stuttgart for the profiling and benchmarking of STAR-CCM+ on petascale computers.
  • Deadlines are fast approaching for the 2014 FLOW-3D Americas Users Conference including early bird registration (01 July), and abstract due date (11 July).
  • You have until 31 August to submit your entry to CD-adapco’s 2015 Calendar Contest. Maybe yours will be the one who gets the most social media votes and wins a cool prize.
  • The second NAFEMS European Conference on Multiphysics Simulation will be held 21-22 October 2014 in Manchester, UK.

Thresholds of Silence

Combining the old and the new, art and science, geometry and aeroacoustics, the Buitenschot Landscape Art Park near Amsterdam’s Schipol Airport uses well planned and deeply cut ridges in the nearby landscape to reduce the propagation of ground level aircraft noise.

Farmers have known for quite some time that deeply plowing a field creates a very quiet landscape. Through study of the noise sources architects designed these V-shaped ridges for the same purpose while at the same time creating a publicly usable green space. Seems like a win-win to me.

The landscape architect calls the ridges the Thresholds of Silence.

P.S. Apologies if some of this news is repeated from last week. I was in a rush and didn’t do a good job separating old from new news.

    The folks at Stanford also released a development version (0.1) of a high-order accurate code called HiFiLES that’s aimed at researchers.

    Thanks for the update on HiFiLES. News about it landed in my inbox just last night so I’ll be sure to mention it.
