| Tackling
Turbulence
with
Supercomputers,
by
Parviz
Moin
and
John
Kim We all pass through life surrounded--and even
sustained--by the flow of fluids. Blood moves through the vessels in
our bodies, and air (a fluid, properly speaking) flows into our
lungs. Our vehicles move through our planet's blanket of air or
across its lakes and seas, powered by still other fluids, such as
fuel and oxidizer, that mix in the combustion chambers of engines.
Indeed, many of the environmental or energy-related issues we face
today cannot possibly be confronted without detailed knowledge of
the mechanics of fluids. |

A

Solution
of
PDEs UG is a flexible software tool for the
numerical solution of partial differential equations on unstructured
meshes in two and three space dimensions using multigrid methods.
Its basic design is flexible enough to support many different
discretization schemes. The underlying distributed dynamic data
programming model offers a smooth migration from sequential to
parallel computing. A number of complex applications have already
been realized. The following sections offer you more information. |
| Flux-Corrected
Transport
(FCT)
Modules Flux-Corrected Transport (FCT) is a
conservative, monotone technique for integrating generalized
continuity and hydromagnetic equations. It is especially useful for
solving compressible-flow problems, particularly those involving
shock and rarefaction waves and contact discontinuities. FCT
accomplishes this objective by combining integration schemes with
low and high orders of spatial accuracy. The low-order scheme
provides a monotone solution, usually by the introduction of
diffusive numerical fluxes, while the high-order scheme provides
high accuracy in regions of smooth flow and shallow gradients. The
high-order solution is obtained by "antidiffusing" the
low-order, monotone solution, but only to such an extent that no new
extrema are created and no existing extrema are accentuated. This is
done by limiting, or "correcting," the antidiffusive
fluxes of the high-order scheme, hence the name Flux-Corrected
Transport. |

Generation
on
the
Web Mesh generation is an interdisciplinary area, and
people from different departments are working on it: Mathematicians,
computer scientists, engineers from many disciplines. Despite the
fact that surprisingly many people are active in the field, often
there are few contacts between researchers. The aim of this page is
to improve communication between research groups and to help people
to get an overview of the field.

| Scalable
Unstructured
Mesh
Computation,
SUMAA3d
Project,
MCS
ANL. Welcome to the SUMAA3D
Project, a collaborative research effort between scientists at
Argonne National Laboratory, Penn State University, Virginia Tech,
and The University of British Columbia. This project was
designed to enable the solution of large-scale applications on
massively parallel machines. To date, many applications have been
unable to take advantage of these machines because of a lack of
publicly available software tools for unstructured mesh computation.
The SUMAA3D project will rectify this situation by providing highly
efficient parallel algorithms and software for the fundamental tasks
of unstructured mesh computation. |
| GRUMMP
The goal of the GRUMMP project is to develop automatic mesh
generation software for unstructured meshes with mixed element
types. The software should produce high-quality meshes that meet
user-defined mesh density requirements, using elements appropriate
for the geometry and physics of a particular problem.
Automatic mesh generation for complex two and three dimensional
domains is a topic of intensive research. It is imperative that
automatic mesh generation tools be capable of generating quality
finite element and finite volume meshes. There must be a balance
between resolution of the boundary and surface features and
complexity of the problem. In addition, for problems with isotropic
physics, element aspect ratio must be small to minimize linear
system condition number and interpolation error. On the other hand,
problems with anisotropic physics (for example, a shear layer in
viscous fluid flow) require highly anisotropic elements for
efficient solution. A further level of complication is that for some
physical problems and applications, quadrilateral (2D) or hexahedral
(3D) elements are preferred, even though filling space with high
quality elements is easier using triangular (2D) or tetrahedral (3D)
elements. |
| 3DMAGGS
The 3DMAGGS code is an elliptic volume grid generator, used to
generate computational domains for Computational Fluid Dynamics
(CFD) analyses of aerodynamic vehicles. It was designed to replace
the GRIDGEN3D code of the GRIDGEN system software, reducing
excessive use of supercomputer resources and provide adequate
flexibility in grid point clustering controls. The 3DMAGGS code has
been derived from the 3DGRAPE code written by Dr. Reese L. Sorenson
of NASA Ames, but has whole host of added and enhanced features. |
| QMG
Mesh

Package The QMG package does finite element mesh
generation in two and three dimensions. The package includes
geometric modeling software, the mesh generator itself, and a finite
element solver. It is free software whose source code is
downloadable from the Web. QMG2.0 runs under Unix and Windows NT. |

| LUGR
Project The LUGR project was carried out in
cooperation with and partially sponsored by the Ground Laboratory of
the RIVM - the Dutch National
Institute of Public Health and Environmental Protection. The aim was
to develop efficient solvers for the numerical simulation of brine
flow for predicting the potential transport of radioactive
pollutants. LUGR methods are meant for the efficient
computation of rapidly varying temporal and spatial solution
transitions by automatic local grid adaptation (more). |

SparseLib++,
IML++,
MV++
. SparseLib++ is a C++ class library for efficient sparse
matrix computations across various computational platforms. The
software package consists of matrix classes encompassing several
sparse storage formats (e.g. compressed row, compressed column and
coordinate formats), and providing basic functionality for managing
sparse matrices. The Sparse BLAS Toolkit is used to for efficient
kernel mathematical operations (e.g. sparse matrix-vector multiply)
and to enhance portability and performance across a wide range of
computer architectures. Included in the package are various
preconditioners commonly used in iterative solvers for linear
systems of equations. The focus is on computational support for
iterative methods (for example, see IML++),
but the sparse matrix objects presented here can be used in their
own right. |
| BlockSolve95
BlockSolve95 is a scalable parallel software library primarily
intended for the solution of sparse linear systems that arise from
physical models, especially problems involving multiple degrees of
freedom at each node. For example, when the finite element method is
used to solve practical problems in structural engineering, each
node typically has two to five degrees of freedom; BlockSolve95 is
designed to take advantage of problems with this type of local
structure. BlockSolve95 is also reasonably efficient for problems
that have only one degree of freedom associated with each node, such
as the three-dimensional Poisson problem. BlockSolve95 is general
purpose; we do not require that the matrices have any particular
structure other than being sparse and being symmetric in structure
(but not necessarily in value). |

| NAFEMS By
the late 1970's and early 1980's, as computing power became more
widely available, increasingly industry was starting to solve
practical engineering problems using finite element analysis
techniques. There was however considerable concern that
the accuracy of the methods, and software implementations, required
to be verified in order to allow the results to be effectively
used. Following extensive lobbying, by industry and academia,
the UK Government's Department of Trade and Industry (DTI) set up,
and funded, a project within the National Engineering Laboratory (NEL),
based in East Kilbride, Scotland, to investigate the issues.
As a result the National Agency for Finite Element Methods and
Standards, quickly shortened to the acronym NAFEMS, was founded as a
special interest group in 1983 with a specific objective namely:
"To promote the safe
and reliable use of finite element
and related technology" |
