The professors who organized this seminar asked me to request that you (or an appropriate delegate) distribute the announcement below to the faculty in your department. The seminar is this Friday, November 10th at 4:30 p.m. in REC 315. Purdue University's Center for Computational and Applied Mathematics(CCAM) Welcomes: Professor Weinan E Department of Mathematics and Program in Applied and Computational Mathematics Princeton University Seminar Title: What Can Go Wrong in Coupled Atomistic/Continuum Simulation Methods? Date: Friday, November 10th / 4:30 p.m. REC 315 This seminar is a part of the center's Visiting Scientist Seminar Series: Fall 2006 Theme "Analysis and Computation of Materials".  We also have some half hour time slots for faculty and/or students to meet with Professor E on November 10th. If anyone is interested in scheduling some time with him, please contact Heather Connell in the CCAM office at 496-7678. E-mail: connellh@math.purdue.edu <mailto:connellh@math.purdue.edu> . Please state your preferred time for a meeting, and CCAM will get back with you to confirm if that time is available. An abstract of his upcoming presentation appears at the bottom of this e-mail. Additional background Information on Professor E: Professor E received his Ph.D. in Mathematics from UCLA. He is currently a Professor in the Dpeartment of Mathematics and Program in Applied and Computational Mathematics at Princeton University. His research centers on developing systematic mathematical analysis and computational methodologies for stochastic and multiscale, multi-physics modeling in science and engineering. Abstract of Upcoming Presentation: Numerical methods based on  coupling atomistic and continuum models hold the potential for simulating  efficiently the behavior of macroscopic systems and at the same time being  faithful to the atomistic details near defects or singularities. However, to  achieve this goal, one needs to understand the numerical issues for  coupling atomistic and continuum models. In this talk, he will discuss  some of the most typical errors in such coupled methods, both for  fluids and for solids, and he will discuss ways of removing these errors. __________________________________ Heather A.
