Second XFEM short course, July 2007, Lausanne, Switzerland

After the success of the course in 2005 (45 participants from 15 countries), the EPFL school of continuing education presents the second XFEM course.



a posteriori error estimation in XFEM


XFEM 2007


Extended finite element methods (XFEM)

EPFL - Lausanne, Switzerland - July 3 to 6, 2007



jointly organized by :

EPFL's School of Continuing Education (SCE);
Department of Civil Engineering - University of Glasgow, and
LIN - Laboratory of Computational Engineering, EPFL.

Since its inception in 1999, the eXtended Finite Element Method, XFEM has been successfully used for various applications in solid mechanics where moving boundaries and singularities are key features of the problem (crack propagation, contact) and multi-physics (multi-fluid, fluid-structure interaction, bioengineering, thermo-mechanics, solidification).

The objective of this course is to promote enrichment-based methods (XFEM, meshfree) for numerical analysis in mechanics. The course is best suited to FEM analysts, Research and Development executives, beginning researchers and will be useful to any company interested in numerical simulation. Students will leave the course with a thorough understanding of the XFEM from the basics to more advanced topics. Specific emphasis will be given to fracture mechanics (damage tolerance assessment, elastic-plastic crack growth, dynamics).

Additionally, participants who so wish are given the chance to participate in a day training on the OpenXFEM++ code, a C++ XFEM library, with special emphasis on fracture mechanics.

A short introduction to enriched meshfree methods will be given, to highlight the differences with the XFEM.

The objective of this meeting is also for the participants to develop their network in the field, build new projects and ventures together, and leave the course with at least one new contact, one new idea, and one new project in mind. The participants are encouraged to prepare a 20mn presentation with the title "How XFEM can help me solve my problem?

This course will be of interest mainly to engineers and research and development executives, as well as beginning researchers from academia. A background in engineering or applied sciences and some previous exposure to finite element methods are necessary for understanding the material covered in the course.

Under the close supervision of the professors, the students will have a chance to implement XFEM on their own into a specially tailored programming interface (MATLAB). This will provide them with a unique insight into the difficulties associated with programming these methods.

Specific times will be allocated for participants to discuss together and with the organisers, during lunches, coffee breaks, and at the end of the teaching sessions.
