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.
