Fourth MPM Workshop

From Jim Guilkey: You are invited to attend the Fourth MPM Workshop.  This year workshop will be held in Salt Lake City, Utah on the campus of the University of Utah, on March 17th & 18th, 2008.  The format will be similar to the previous workshops,  held at University of Utah, Oklahoma State University and Sandia National Laboratory, where relaxed environments facilitated understanding and awareness of the MPM's strengths and  weaknesses via informal talks and discussion.  Topics of interest include, but are not limited to, numerical implementation and properties, algorithm properties, variations and additions, and  applications.  Please feel free to pass this announcement along to other potentially interested colleagues.

Student participation is welcomed and encouraged.  In order to facilitate healthy student involvement, Tim Bartel at Sandia National Laboratory will be sponsoring Student Housing Fellowships, which will cover the cost of two nights at the University Guest House, a hotel adjacent to the University of Utah campus.  A generous, but limited, number of fellowships are available.  Please contact Tim or me if you are interested.  A block of rooms will be reserved there for all participants, and information on that will be forthcoming, once a level of interest has been established.  Transportation between the Guest House and the meeting venue will be provided.

Please respond with a talk title by February 2 if you'd like to participate.  In the meantime, I'd love to hear from anyone who tentatively (or definitely) plans to attend, to get an idea of how many to expect.

Thanks, and we hope to see you in Salt Lake City!
