Tecplot 360 2012 Released

Automatically seeded streamlines can reveal flow features in Tecplot 360 2012.

Tecplot announced the latest release of their flagship CFD visualization product, Tecplot 360 2012. This update includes an ANSYS CFX loader, an improved ANSYS Fluent loader, automatic seeding of streamtraces, and slices with constrained extents.

Symscape Offers Another Preview of Caedium v4

Compressor passage simulation in Caedium v4

Symscape has provided another “sneak peek” of Caedium v4, the upcoming release of its OpenFOAM-based CFD software.  v4 will include a new cyclic boundary condition, improved tolerancing for forming watertight volumes, and modeling of thin surfaces.

Applications & Other

Meshing

  • When I think of a Voronoi diagram it’s just in the context of meshing. But when they’re interactive the results are rather interesting.
  • In the debate between history-based and direct CAD modelers, direct modeling is being positioned as a tool for performing “cosmetic surgery” on CAD models prior to FEA simulation.
  • Here’s part 2 of the NX video series on FEA workflow.

Not CFD

  • Google Graphing: You can type a 2-variable equation into Google and get a 3D interactive plot of the results. Might be handy for quickly plotting CFD-related functions.

  • Geomagic Acquires Sensable: Geomagic, the software company with products for working with point cloud data and turning it into faceted or analytic geometry, has acquired Sensable, the hardware company with a haptic device that provides touch-feedback when working with 3D geometry.
  • NASA Released VSP: NASA released Vehicle Sketch Pad (VSP), their software for rapid 3D modeling of aircraft, as open source. See  OpenVSP.org for details.
  • If you are a CAD or CAE blogger, TenLinks wants you to join their TEAM advertising consortium.

Underwater Ink Photography

Italian photographer Alberto Seveso used high-speed photography to capture images of two streams of colored ink mixing in water. The results are spectacular.
