A Very Successful Workshop

This blog is so overdue, since the Workshop concluded nearly six months ago! But better late than never. So here I am, giving you an much delayed update.

After several years of planning, the 1st International Workshop on High-Order CFD Methods was successfully held in Nashville, Tennessee, on January 7 and 8, 2012, just before the 50th Aerospace Sciences Meeting. Over 70 participants from all over the world across the research spectrum of academia, government labs and private industry attended the Workshop. Many interesting results were presented. The major findings from the Workshop include:

1.     For problems with smooth solutions and geometries, high-order methods are able to demonstrate high-order accuracy with h and p-refinement. High-order methods demonstrated better performance than the 2nd-order finite volume method for both steady and unsteady problems based on error vs. cost.

2.     For problems with non-smooth solutions or geometries, high-order methods cannot achieve high-order accuracy as expected. They are comparable to low order methods in performance.

3.     Solution based hp-adaptations have been shown to be very effective in minimizing the computational cost to achieve a given level of accuracy.

4.     For RANS simulations, high-order methods are still not as robust as low order methods in converging to the steady state solution. It is believed that this behavior is related to non-smoothness introduced in the turbulence models.

If you are interested in doing research on high order methods, the following pacing items may interest you:

1.     High-order mesh generation

2.     Solution based hp-adaptations

3.  Scalable, low memory efficient time integrators for RANS and hybrid RANS/LES approaches

4.     Robust, accuracy-preserving and parameter-free shock capturing

Some of the abstracts of the workshop are contained here:

The next workshop will be held in Cologne, Germany next summer. Check the workshop

On a personal note, I will join University of Kansas as the Spahr Professor and Chair of Aerospace Engineering in August 2012. It was a difficult decision, but I do look forward to the new challenges ahead.


  1. We at Auroraare trying to join theList Top Engineering Collegesby creating new practices in the Engineering Education in India. We request you all to have a look and let us know how we can improve our quality of deliverables.

  2. ZJ: Congratulations on the chair position at UK.

  5. Hi, I came across your blog on my google search about CFD jobs.
    I'm have a MS degree in Chemical Enigneering and my thesis was about Multiphase Flow CFD, when I come to job market, I feel doomed...
    I graduated this May and looked for CFD jobs for a while and got no good news... my biggest problem is I'm fresh out of school with no experience, I have good GPA and 1 publication but it does not help at all.....

    Now I'm wondering CFD jobs are only for PhDs, is that right? or overall demand for CFD people is low....
    I'm planning to apply for PhD programs now, but I don't know if CFD is a dead end when it comes to job market for Chemical Engineers. I liked CFD, but I don't want to suffer from terrible job searching again like I'm doing now...
    Should I give up CFD?

    Thanks for your advice if you see my message...

  6. Maybe this is related to Chemical Engineering? All my students (in mechanical or aerospace engineering) with MS or PhD degrees found jobs, many with job offers before they graduated. I also know people in the industry and that has helped too. Did you try the CFD-online web site? It has a lot of jobs posted.

    I know very little about chemical engineering, though. For AE or ME, there are a lot of CFD jobs out there.

    Best luck!
