NEW TEXTBOOK DOWNLOAD (January 25, 2010)
Finite-element Methods for Electromagnetics is a 320 page textbook. With over 160 exercises, it is well suited to self-study or classroom use. The PDF version is an update of the text Field Solutions on Computers (CRC Press, Boca Raton, 1997). It is the perfect companion to our TriComp programs for those who want a deeper understanding of the underlying physics and numerical techniques. The text emphasizes finite- element techniques to solve real-world problems in research and industry. After introducing numerical methods with a thorough treatment of electrostatics, the book moves in a structured sequence to advanced topics. These include magnetostatics with non-linear materials, permanent magnet devices, RF heating, eddy current analysis, electromagnetic pulses, microwave structures, and wave scattering. The mathematical derivations are supplemented with 167 chapter exercises and comprehensive reviews of the underlying physics. The book also covers essential supporting techniques such as mesh generation, interpolation, sparse matrix inversions, and plotting routines.
WINDOWS 7 (January 25, 2010)
All software packages have been tested and are 100% compatible with Windows 7.
NEW EDUCATIONAL SOFTWARE: KB (November 1, 2009)
KB is a comprehensive package of reference material and computer codes to model materials at high temperature and pressure. The Windows programs, available at no charge to educational institutions and industries, may be used in computer laboratories or distributed to students. The package is of particular interest to physicists, mechanical engineers and civil engineers. It provides students with a hands-on introduction to the hydrodynamic equations, the equation of state and critical concepts like the Hugoniot curve. The 130-page instruction manual reviews shock and detonation physics and includes an array of benchmark tests to illustrate accuracy issues in nmuerical modeling.
NEW PRODUCT: FE Builder (FEB0100) (October 5, 2009)
Finite-element methods have extensive applications in areas such as mechanical engineering, electrical engineering, physics research, fluid dynamics and bioengineering. While the methods are straightforward to implement for a wide variety of physical problems, researchers and students face two obstacles to their implementation: 1) creation of quality conformal meshes for arbitrary application geometries (mesh generation) and 2) efficient analysis of a large amount of numerical output data (post processing). Creating user programs to accomplish these tasks could involve man-years of effort, while commercially-available mesh generators are expensive and are often inflexible and proprietary. FE Builder solves both problems, allowing developers to concentrate their attention on finite-element solutions. The package includes a solid-modeling graphical environment, an automatic conformal mesh generator and a fully-customizable universal postprocessor. FE Builder is well-suited for one-of-a-kind research applications as well as commercial distribution of finite-element packages.
NEW FEATURE: GEOMETER (June 27, 2009)
Geometer is now a full featured STL viewer with advanced editing features. The STL format for complex solid objects is the standard for computer controlled machining operations (3D printing).

You can load up to 50 objects for display. Geometer also has editing features to scale, reflect and shift STL objects.
NEW VERSION: AETHER (February 18, 2009)
Version 2.0 features greatly expanded plot capabilities, new interactive analysis tools and more tutorials. The program will be available March 1, 2009. A purchase of Aether 1.0 includes a free update.
NEW VERSION: WAVESIM (February 8, 2009)
WaveSim 6.5 is the complete tool for 2D frequency-domain electromagnetics. You can design resonant cavities and antennas, characterize microwave devices and perform high-frequency scattering simulations. We revamped the program, adding new commands to make setup easier and extensive tutorials.
