Numerical Methods
The research in computational fluid dynamics (CFD) in the
early years of The Fluid Dynamics Group (T-3) at Los Alamos National Laboratory
was prolific (history), even though any
development was significant when so few methods were
available. A comparison of early T-3 work with current research illustrates
that many of the same methods are still fundamental, and modern advances
in CFD are often improvements on older techniques.
Current contributions to CFD are also directed towards developing new
material models, integrating a wider variety of physics and applications
to complex systems. The combination of more powerful computers with more
sophisticated simulation tools have addressed problems that could not
have been considered just a decade ago.
The following is a list of numerical methods and schemes which have been
developed, refined or implemented over the last few decades. A summary
of CFD concepts and methods is available (numerical
methods notes (pdf, 410k)) as a introduction to the novice.
We apologize in advance: the links to the various methods will be developed
as online resources become available.
