This paper discusses the application of multigrid techniques to the solution
of implicit well equations, which arise in the numerical simulation of oil
reservoirs.  The emphasis is on technqiues which can exploit parallel
computation.

Abstract

The multilevel adaptive iteration is an attempt to improve both the robustness
and efficiency of iterative sparse system solvers.  Unlike in most other
iterative methods, the order of processing and sequence of operations is not
determined a priori.  The method consists of a relaxation scheme with an
active set strategy and can be viewed as an efficient implementation of the
Gauss-Southwell relaxation.  With this strategy, computational work is focused
on where it can efficiently improve the solution quality.  To obtain full
efficiency, the algorithm must be used on a multilevel structure.  This
algorithm is then closely related to multigrid or multilevel preconditioning
algorithms, and can be shown to have asymptotically optimal convergence.  In
this paper the focus is on a variant that uses data structures with a locally
uniform grid refinement.  The resulting grid system consists of a collection
of patches where each patch is a uniform rectangular grid and where adaptive
refinement is accomplished by arranging the patches flexibly in space.  This
construction permits improved implementations that better exploit high
performance computer designs.  This will be demonstrated by numerical
examples.

AMS subject classification:  65N55, 65N50.

Key words:  Multigrid, domain decomposition, adaptive, iterative methods.

Subject: Position at University of Kentucky

The Department of Mathematics at the University of Kentucky invites
applications for at least one tenure-track Assistant Professorship to begin in
Fall 1997 (subject to budgetary approval.) We are interested in applicants in
the areas of numerical analysis and algebra/number theory.  However,
applications in other areas are also welcome.  We are especially interested in
applications from women and minority groups.  Using the AMS application cover
sheet (if possible), applicants should submit a vita, a description of
research and future plans, evidence of effective teaching, and arrange to have
at least three letters of recommendation sent to:  Chair of the Recruiting
Committee, Department of Mathematics, 715 POT, University of Kentucky,
Lexington, KY 40506-0027.  The deadline for submission of applications is 31
January 1997.  We expect to begin evaluating applications 1 December 1996.

    Editor's Note: I hear they are looking for someone with a background in
    -------------  finite elements/volumes, multigrid, domain decomposition,
                   and possibly parallel computing to work with a well known
                   multigrid person who is moving there in January...

The Jackson Hole Area and Recreation:
 
         Located in Northwestern Wyoming, Jackson Hole is a beautiful
         alpine valley ringed on all sides by mountains. The Grand
         Teton Range on the east, and the Absaroka on the north. The 
         elevation of the valley ranges from 6,200 feet to 6,800 feet
         with some of the surrounding mountains attaining heights of
         over 13,400 ft. The average high temperature in July is 79 
         degrees and the average low is 41 degrees.
 
         Jackson Hole has unlimited recreational opportunities. Grand
         Teton National Park, the National Elk Refuge, and Yellowstone 
         National Park are but a few of the nearby attractions. These
         public lands afford an abundance of hiking, fishing, hunting,
         wildlife viewing, white water rafting, camping, biking, and 
         just plain old outdoor fun. Twenty-mile long Jackson Lake, 
         at the foot of 12,065 Mt. Moran, is popular with water skiers
         and sailors as well as fishermen. The Jackson Hole area is a
         photographer's paradise. Tennis courts and two 18-hole golf
         courses are also available.

         The Old West is still alive in Jackson Hole where you can take a
         stagecoach ride through town or enjoy the rodeo.
 
         In addition, Jackson Hole boasts a fascinating array of art
         galleries, history museums, featuring the renowned National
         Wildlife Art Museum, and shops. The Grand Teton Music Festival
         performs in the summer, featuring musicians from all over the world.

I am pleased to announce that the FIRST AFOSR INTERNATIONAL CONFERENCE ON
DNS/LES (FAICDL), sponsored by the US Air Force Office of Scientific Research
(AFOSR), will be hosted by Louisiana Tech University, Ruston, Louisiana, USA
on August 4-8, 1997.

As computers become more powerful, direct numerical simulation (DNS) and large
eddy simulation (LES) become more and more important and viable for the
prediction and control of transitional and turbulent flows on complex
configurations.  The conference encourages participants to present all topics
related to DNS and LES which include:

. DNS/LES toward understanding fundamental flow physics
. DNS/LES for complex flows
. DNS/LES for flow transition
. DNS/LES for fully developed turbulent flow
. DNS/LES for aeroacoustics
. DNS/LES for heat transfer applications
. DNS/LES for combustion applications
. LES for for atmospheric boundary layers
. DNS/LES for engineering applications 
. DNS/LES for transition and turbulence modeling
. Development on filter and subgrid model for LES
. Boundary condition treatment for DNS/LES
. Numerical algorithm developments for DNS/LES
. Parallel computation implementations/applications for DNS/LES 

The organizers encourage scientists, engineers, and graduate students in the
DNS and LES community from all continents to present their reviews,
state-of-the-art technique, and/or numerical results as well as to discuss the
future development of DNS and LES.  The conference is open to any individual
and organizations.

A number of leading researchers from Europe, Asia, Africa, and North America
have accepted invitations to serve as scientific committee members and/or give
invited lectures.
