Summary Report

 

The rapid development of the boundary element method (BEM) in the last decade has significantly broadened the applications of the BEM and the related methods. Many challenging computational problems such as multi-scale and large-scale modeling of advanced materials, structures, fluids, and MEMS/NEMS can now be modeled by the BEM effectively, thanks to the advances of the various fast solution methods. While the BEM related research are thriving in Europe, Asia and South America, the research activities related to the BEM in the US have been dwindling since the beginning of this century. There is an urgent need of retraining researchers, engineers and students in the US on the recent developments in the BEM and its emerging applications, to help further advance the research and broaden the applications of the BEM in the US.

 

Sponsored by the US National Science Foundation, a workshop on the BEM was held on The University of Akron campus (in the suburb of Cleveland, Ohio, USA) during September 1-3, 2010. This workshop had a two-day short course sequence on the basics of the BEM and a one-day symposium on the emerging applications and future directions of the BEM. About 50 researchers and engineers around the world and students across the US attended this workshop.

 

The workshop started with a two-day short course sequence for students, researchers and engineers on the fundamentals of the boundary integral equation (BIE) formulations and the BEM in applied mechanics, the basics of the Greenís functions, the symmetric Galerkin BEM, and the new fast multipole BEM. Following the two-day short courses, a one-day symposium focused on discussions of emerging applications and future directions of the BEM. Invited speakers from around the world opened the topics, presented many examples of emerging applications of the BEM in engineering and science, and led discussions on the future directions in the BEM.

 

Fellowship support were awarded to 17 students from 14 universities in the US to support them for participating this workshop. A competition of poster presentations for students was also held. This workshop has brought leading researchers around the world to the US to discuss the emerging applications and the future directions of the BEM, helped to train a new generation of students in the research on the BEM, and to connect US researchers and students with those from other countries and from national labs and industries.

Poster Competition Awards

 

Eighteen students participated in the competition of poster presentations during the workshop. These posters covered a wide range of research topics in computational science and engineering. All the 18 posters were reviewed by seven judges. Based on their excellent research efforts, approaches, results and presentation skills, the following three students were selected as the winners of the poster competition at the workshop:

 

Zhangli Peng, University of California San Diego:

Multiscale modeling of red blood cells in Stokes flows by coupling finite element and boundary element methods

Sofie Leon, University of Illinois at Urbana-Champaign:

††††† Adaptive dynamic fracture using nonlinear cohesive zone modeling

Han Tran, The University of Texas at Austin:

††††† A weakly-singular SGBEM for analysis of cracks in 2D multi-field media
