Nero2d and wxGBTool version 2.0.2 have been released.

Introduction

Open FMM is an open source electromagnetic software project for scattering at very large objects. It currently consists of a fast parallel two-dimensional TM/TE solver called Nero2d. The solver is capable of handling extremely large problems. Nero2d makes use of an asynchronous implementation of a parallel Multilevel Fast Multipole Algorithm (MLFMA).

2D Features

Two-dimensional solver: Nero2d

Nero2d is a TM/TE solver for scattering at a number of two-dimensional cylindrical dielectrics or perfect electric conductors (PEC) of arbitrary shape. The objects can be embedded into each other so coatings can be taken into account. As illumination, Nero2d supports plane waves, line sources and higher order Gaussian bundles. Several types output can be specified such as the electrical field in a specified region or the bistatic radar cross-section. Using its parallel engine, it can solve problems up over one million of wavelenghts in diameter with several tens of millions of unknowns. Even on a single processor, it can easily solve practical problems with hundreds of thousands of unknowns in a short amount of time.

Graphical User Interface: wxGBTool

For ease of use, a graphical user interface (GUI) has been developed for Nero2D in which the user can specify the geometry. Special support for some lens types has been incorporated, however, the user can specify any number of aribtrary shaped polygons. The GUI has an intuitive interface, allowing for a flat learning curve of the software.
