Post-doc position opening

Position Summary:
Perform basic research in the field of ship motions as well as experimental and computational fluid dynamics in the Dr. Leigh McCue-Weil’s research lab. Research expertise in either RANS or meshfree CFD approaches such as SPH with interest in both approaches and/or expertise in experimental fluids. Job responsibilities will require strong experience with computational and experimental components. Post-doc will work with Dr. McCue-Weil in preparing reports to the research sponsor, writing journal and conference papers, and presenting in conference and other open forums.

Required Qualifications:
Ph.D. in ocean/naval/aerospace/mechanical or related engineering discipline, as well as knowledge of, or experience in, CFD and experimental fluids.

Preferred Qualifications:
Experience with OpenFoam, SPHysics or other mesh-free Lagrangian CFD approach.

SCraMP Comparison Data

Folks often inquire about the accuracy of using an iPhone’s sensors as a data acquisition system.  John Zseleczky from the U.S. Naval Academy Hydromechanics Laboratory recently conducted a very nice comparative study resulting in the attached data and has given me the go-ahead to share this publicly.  Thank you very much John Z. and the USNA!

Underwater Gas Expansion and Deflagration

The underwater combustion of a propane-air mixture in an acrylic cylinder is captured on the video linked here from multiple angles. This experiment, led by Van Jones with assistance from Kariann Vander Pol and John Gilbert, is designed to provide visual data and pressure time-histories for future CFD validation studies. We have submitted this to the APS Division of Fluid Dynamics gallery of fluid motion competition this year! More information, including an extended abstract and higher resolution version of the video can be found at:

SCraMP Release 3.13

I am often asked if SCraMP can be useful on big ships as well as the small craft, for which it is named.  My answer is always a resounding yes!  There is nothing in the code that would confine it to small craft, and indeed, I have tried to make it as customizable as possible to suit a range of needs.  With that in mind, the latest SCraMP release, hitting the app store today (, adds two new safety metrics, one to help identify possible parametric roll conditions and one to provide guidance as to whether or not conditions might be making passengers sensitive to motion sickness.  As always, if you have suggestions for app improvements or feedback on SCraMP v3.13, I am eager to hear from SCraMPers.



SCraMP and iOS7

SCraMP users, a bug has been identified with the use of the safety metrics screen of SCraMP when running iOS7. I have submitted to Apple an update to solve the problem and hope to have the new iOS7 version of SCraMP released to you next week. Apologies for any inconvenience in the meantime.
