Celeritas Simulation Technology announces the commercial availability of Suggar++, a general purpose overset grid assembly code. Suggar++ can be used as a pre-processor for static configurations or coupled with the overset flow solver for time dependent simulations. The software supports both structured and unstructured overset grids.

SGI’s CTO Predicts Broader Use of CFD in 2012

Dr. Eng Lim Goh, chief technology officer at SGI, offered in an article at Bio-ITWorld.com ten predictions for high performance computing during 2012.  He prefaced these predictions with an opinion that we are transitioning from an information age to a knowledge age. One prediction is a broader use of CFD based on its track record of replacing costly testing of physical prototypes with simulations of everything from rockets to arteries. In particular, he predicts CFD will find practical application in “systems biology” during 2012. [Keep in mind the forum in which this article appears. Also keep in mind that SGI acquired open-source CFD solver OpenFOAM last year.]

Other predictions include personalized medicine, severe weather prediction, and proofs of black hole evaporation.

Science Proves Bees and Dragonflies Really Can Fly

A Cornell University professor has used a two-dimensional simulation of the unsteady Navier-Stokes equations to show that insects like bumblebees and dragonflies are able to fly through the interactions with vortices produced by their flapping wings.

This NSF-funded study was performed in 2D. Work on 3D simulations is underway.
