Macsyma Inc. Announces Release 3.0 of PDEase2D Finite Element ------------------------------------------------------------- Software with Scientific Notebooks ---------------------------------- ARLINGTON, MA (October 21, 1996) - Macsyma Inc. will ship Release 3.0 of PDEase2D(tm) finite element analysis (FEA) software on November 7, 1996. The new release for Windows 95(tm) and Windows NT(tm) adds a scientific notebook interface that includes interactive animated graphics, a DataViewer(tm) for displaying and editing numerical data, text processing, hypertext links, and a filter for importing drawings from major CAD packages such as AutoCAD(R). PDEase2D is extremely flexible and easy to learn. It solves problems in heat transfer, solid mechanics, reaction/diffusion, fluid mechanics, electromagnetics, groundwater flow, quantum mechanics, and other fields. "PDEase2D now combines the convenience of scientific notebooks with the flexibility of a highly automated finite element engine. We designed PDEase2D so people can focus on engineering applications, rather than on finite elements," said Macsyma Inc. President and CEO Richard Petti. PDEase2D's simple input language, automatic grid generation and refinement, on-line help, and 140 working on-line demonstrations dramatically reduce the time required to solve nonlinear static, dynamic, and eigenvalue problems with up to 32 simultaneous equations plus constraints. PDEase2D uses the same scientific notebook interface as another Macsyma Inc. product, Macsyma(R) mathematics software. Macsyma software can be used to pre-process complicated equations for solution by PDEase2D and to post-process data generated by PDEase2D. Macsyma Inc. is offering its new PDEase2D product at an introductory price of $699 until January 1, 1997. Founded in 1992, Macsyma Inc. develops, markets, and supports PDEase2D finite element analysis software and Macsyma general purpose math software. ____________________ PDEase(R) and Macsyma(R) are registered trademarks and PDEase2D(tm) and DataViewer(tm) are trademarks of Macsyma Inc.

It solves static, dynamic and eigenvalue problems with up to 32 (non)linear partial differential equations (PDEs) plus constraints with an unlimited number of nodes in two space dimensions plus time. PDEase2D also includes 140 worked sample problems from many fields, so you can often solve your problem by modifying a sample problem. 2 ACCESSIBLE With PDEase2D's remarkably simple input language, you specify only the PDEs, variables, geometry and boundary conditions; PDEase2D creates both numerical output tables and plots. PDEase2D generates and refines the element grid, adaptively selects time step size in dynamic problems, and iterates until it attains convergence in nonlinear problems. Because PDEase2D does automatic error analysis, you don't need to make several runs with different meshes to verify convergence. And you can choose whether or not to override the automatic defaults. 3 SCIENTIFIC NOTEBOOKS PDEase2D's input and output appear in attractive scientific notebooks with interactive animated graphics, numerical data tables, formatted text, hypertext links, and an active table of contents. 4 GRAPHICS PDEase2D creates many kinds of interactive animated Windows graphics, right in the notebooks. You can create animations of solutions to dynamic problems, and run them dynamically or frame by frame. 5 PRE-PROCESSING AND POST-PROCESSING You can import geometries from CAD programs. You can use Macsyma (a separate symbolic numerical software product from Macsyma Inc.) to post-process the numerical output produced by PDEase2D right in the shared notebook interface. For complicated equations or coordinates, you can use Macsyma to write the PDEs automatically and pass them to PDEase2D for numerical solution. -------------- PDEase2D runs under Windows 95 and Windows NT. A version of PDEase2D without notebooks runs on SPARC workstations.

The book includes problems involving gravity, electricity and magnetism, heat conduction, elastic deformation and fluid flow. These problems all involve solving (systems of) partial differential equations (PDEs) by finite element analysis (FEA). Using this book and the PDEase software, the reader can focus on the actual physics of problems rather than on numerical methods. Engineers, scientists and students who can express a problem in terms of PDEs can profit from this book. Besides providing an introduction to solving problems with PDEase software, the book offers insight into many interesting phenomena in classical physics as well as the power of FEA. This book will be helpful to advanced undergraduates, graduate students and practicing engineers and scientists who need to solve problems involving PDEs. Table of Contents 1.
