Dr. B. Herbst of the University of the Orange Free
State, South Africa, will speak on ``Moving Finite Ele-
ment Methods (MFE's) in One Space Dimension.''
TIME: 3:30 PM
ROOM: MC 6091A
ABSTRACT
MFE's are devised for using uneven grids with time
dependent problems. It allows the nodes to cluster and
move in time in such a way as to ensure the most accu-
rate numerical solution that can be obtained for a
given number of elements. In this talk it will be
shown that MFE's are particularly useful to track down
shock structures. Burger's equation u sub r + u u
sub n = epsilon u sub nn , and the inviscid Burger's
equation u sub r + u u sub n = 0 , will be used as
models to illustrate the salient features of the
methods.
