Therefore it is called a Time-Space-Synchronized FDTD algorithm (TSS FDTD, or in short, TSS). It uses a non-staggered grid to give simulation results in a time and space synchronized manner.To my surprise the new algorithm is better than the current FDTD in many major aspects, as explained below. Since I am just playing with FDTD, not using a grant to do research, I did not bother to do a thorough research but simply came up with my owner solution. I did a quick search over the internet and did not find an answer. One thing I found strange was that the field simulation results provided by an FDTD method could not be used to do calculations such as field energy transfer and field divergence. Among the coding I played is Schneider’s teaching book “Understanding the FDTD Method” ( ). To know more about this software, read software specifications at Time-Space-Synchronized FDTD Simulation To get a rough idea of what the software does, read a test report at You can review source code of these sample plugin modules to see how you can develop your own plugin modules. Tine-Space-Synchronized FDTD algorithm for inhomogeneous environments.Time-Space-Synchronized FDTD algorithm for homogeneous space.Sample plugin modules are part of this open source project.įollowing FDTD algorithms are implemented as FDTD algorithm plugin modules: You try your ideas and coding by deriving new classes from these abstract classes. It is not intended to be a software product rather, it uses open source to provide a framework and tools for you to experiment your own ideas and coding.įor simulating EM fields, a simple plugin system is used to dynamically load following modules: FDTD algorithms, boundary conditions, initial field values, field sources, and total field/scattered field boundary.īy using this plugin system, you can experiment on different ideas and coding of these elements in a field simulation.įor the simulation system, each plugin module is represented by an abstract C++ class. The purpose of this software is for doing digital experiments on electromagnetic fields, such as simulations, statistics, FFT, 3D/2D drawings, etc.
