Features

At present, software has the following features:

• both command line and graphical user interface version available,
• running 3D FDTD on processor (CPU) or graphics cards (GPU),
• support for multiple threads on processor,
• up to 80 times faster calculation on GPU than on CPU,
• use of several Yee algorithm implementations (depending on material parameters) to save memory and time,
• reflecting and absorbing boundary conditions (Liao, CPML), periodic boundary conditions,
• point sources, total/scattered field source,
• plane wave and focused source spanning over layers (infinitely extending media),
• time domain Near-Field to Far-Field transformation,
• different materials (linear, PEC, RC, ADE and PLRC based),
• predefined database of optical properties for more of 150 different materials
• computational geometry input from simple geometric entities, Tetgen tetrahedral mesh or Gwyddion height fields
• output to Gwyddion files (see http://gwyddion.net) and other different output possibilities (e.g. local absorption).

More algorithms are being added successively.
