Title: Textbook Multigrid Efficiency in Computational Fluid Dynamics

Time:  Friday March 1,2002, 2:30 pm.  Room: Burnside 1205

In this talk, I am going to briefly outline the basic multigrid ideas 
and their applications to solution of PDE.  The concept of distributed 
relaxation will be discussed in more details.  A general framework for 
achieving textbook multigrid efficiency (TME) in solution of the Navier-Stokes 
equations will be presented. Some numerical results confirming TME for 
distributed-relaxation solvers will be demonstrated for viscous incompressible 
and subsonic compressible flows with boundary layers and for inviscid 
compressible transonic flows with shocks.
