     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.
