Input file 1: commands and parameters
Be careful: Although most sequences of functions are not important, the function $NumberofObject MUST appear before the function $MaterialStructure and $MaterialParameter.
Files setting
Unit setting
Time setting
Space setting
Source setting
Material setting
Near-to-Far-Field setting
Generation setting
Gmsh setting
For more information about Gmsh, see Gmsh website.
Input file 2: commands and parameters
Note: You can run the FDTD program WITHOUT the input file 2. However, if using this, you should really know the meaning of each function and parameter; otherwise, the program may not execute correctly as you change any default parameter.
The format of output files
These pages present text format.
XX means it could be Ex, Ey, Ez, Hx, Hy, or Hz.
And n represents the time step.
ii is ii-th file.
