"Aladdin is a computational toolkit for the interactive matrix and finite element analysis of large engineering structures." It is being developed at the University of Maryland Institute for Systems Research and is funded by the National Science Foundation and Federal Highway Administration. Aladdin has numerous functions, including matrix arithmetic, structural analysis, and mechanics of finite elements. The software is excellent for use by both student and professional engineers. Extensive information and publications are given on the Web site, providing a good overview of the package. The Aladdin source code is available for download after a free registration. It can be compiled under UNIX operating systems, and special instructions are given for use in Windows.
