High-Order CFD Workshop


Merry Christmas and Happy New Year!

Hello again after a long silence. The last few months were quite hectic. In addition to our daily activities, we had several prominent visitors to aerospace engineering, including a three-star general, a NASA astronaut, a top Boeing executive. In fact, the general was interested in seeing some CFD. I therefore got to shake his hand. I also had the pleasure of visiting South America for the first time, as a matter of fact, the largest country there - Brazil. I really enjoyed Brazil and will definitely visit again. Here is a photo of Sao Paulo.


Oh yes, another big event in town was the the biggest upset in ISU's football history - we beat Oklahoma State!

Now back to CFD...

The 1st International Workshop on High Order CFD Methods will be held in Nashville on Jan. 7 and 8, 2012. Many types of high-order methods will be covered by researchers from all over the world. We will have two full days of actions. See the following agenda for details:

Here is a bit of history regarding the Workshop. I became a member of the Fluid Dynamics Technical Committee of AIAA in 2006-2007, and then started to chair the CFD Algorithm Discussion Group (DG) until 2010, when Dr. H.T. Huynh of NASA Glenn took over.  The charter of the DG has been:

To coordinate research and promote discussion for the improvement of CFD algorithms with a particular focus on:
       i.     High-order spatial discretization
       ii.     Error estimate, grid adaptation and methods capable of handling bad grids
       iii.     Efficient time marching/iterative solution methods for unsteady flow
       iv. Benchmark and challenge problems for above methods

Many leading CFD pioneers and experts including Jameson, Roe and van Leer participated in various discussions. The workshop idea came from one of the many discussions, and was also shared by the ADIGMA project in Europe. A strong support has been provided by AFOSR and DLR of Germany. Through several years of hard work, the DG has achieved two major milestones:

1. Identified three pacing items based on a survey and numerous discussions - discontinuity capturing, hp-adaptations and low storage efficient solver. Details are given in the following presentation.

2. The planning of the high-order workshop.

Let's hope we will have a very successful Workshop in Nashville!
