I am doing simulation of flows which has a wide range of seppd and from some reference i know it is best to use Arbitrary Lagrangian-Eulerian method, but in our university, i can not get any information in it, so a ask for help, Wolud you please telling me where to get some information on this method. You can also mail me a e-paper. Thanks

Hi LiQiang, I can indicate you these papers:

-Hirt, C.W., A.A. Amsden, and J.L. Cook, "An Arbitrary Lagrangian-Eulerian Computing Method for All Flow Speeds," J. Comp. Phys., Vol. 14, p. 227, 1974.

-Amsden, A.A., H.M. Ruppel, and C.W. Hirt, "SALE: A Simplified ALE Computer Program for Fluid Flow at All Speeds," Los Alamos National Laboratory Report LA-8095, 1980.

Also, you may want to look for KIVA-3v2 which is derived by SALE. It is distributed by NEA (www.nea.fr) to universities, researchers and research institutes. A paper introducing the code is

-Amsden, A.A., "KIVA-3: A KIVA Program with Block Structured Mesh for Complex Geometries," Los Alamos National Laboratory Report LA-12503-MS, March 1993.

hi, Andrea:

But how can I get the Los Alamos National Laboratory Reports? I don't think they can be published publicly.Do you have some ways for getting it?

Thanks!

Hi I had not checked this forum in ages, so I hope this is not too late. You may find the following papers useful and some are avaialable on line.
