boundary element

Dear BEM experts:

I am trying to find a boundary element solution for the problem of a cavity in an infinte space. The boundary condition is such that the cavity boundary is subjected to a constant radial influx. I have used the standard fundamental solution for the interior case (finite domain). The results, I obtained for the potential were reasonable for points inside the exterior region. However, on the boundary, the results for the potential were in the order of 10^12 (instead of zero value)!!

Any idea what went wrong. Thanks.

ES 240 Problem 6

Submitted by Cai Shengqiang on Fri, 10/05/2007 - 02:06

I have got the master degree of Solid Mechanics in University of Science and Technology of China. Actually, I have taken several courses related to this subject, such as strength of materials and the theory of elasticity. So, my strength may be that I have some knowledge about it, but my poor ability to solve PDE or even ODE could be the specific obstacle for studying this course. I will do research in Suo’s group(http://www.seas.harvard.edu/suo/), and my research may be related to soft matters, such as gels.

Can anybody tell whether there is any closed form solution for Green's function in an anisotropic material? If yes it would be great if you share some of the literatures on this topic.

Hi,
I am currently working as a Design Engineer-CAE in Bangalore,India.Presently interested in doing a MS/Mtech in the field of Mechanical Design and analysis through a distance learning program/part time course.It would be great if someone suggests an university(in India/abroad) where these kind of courses are offered.
Regards,
Ankita

The 20th Annual Melosh Competition for the Best Student Paper on Finite Element Analysis will be held at Duke University on April 25, 2008. The competition has become one of the premier graduate student events in the broad area of mechanics. We have held the competition at a variety of locations over the past several years, and this year we are returning to Durham.
