AutoMesh: an automatically adjustable, nonuniform, orthogonal FDTD mesh generator

In this article, we introduce a three-dimensional, automatically adjustable, non-uniform orthogonal-mesh generator, AutoMesh, developed using a Windows application-development package, Microsoft Visual Basic. The developed mesh-generating package can efficiently produce geometrical and material data files for a complex electromagnetic configuration that serve as inputs to a generalized non-uniform finite-difference time-domain (FDTD) Maxwell's equations solver. In addition, the fruitful graphical functions of the package insure not only the accuracy of the generated data files, but also the ease of mesh generation for complex objects. Herein, we first present the algorithm of mesh generation, and then illustrate graphical features of the package.
