FDTD_make_figani

SALMON has a FDTD functionality to solve electromagnetic problems. This program, FDTD_make_figani, is a tool to make figures and animations from the results obtained by the FDTD calculation of SALMON.

Requirements

• Python 3
• NumPy
• matplotlib
• ffmpeg

If you are windows user who uses python for the first time, I recommend to install WinPython that includes all requirements for this program.

Usage

make_figani.py is an executable file. figani.inp is an input file. make_figani.py and figani.inp must be in the same directory. When you use WinPython, open make_figani.py by Spyder that is included in WinPython, and push F5 key.

The input parameters are as follows:

• dir_name
  Name of directory that includes the results obtained by SALMON. Default is './'.

• make_ani
  Enable('y')/disable('n') making an animation file. If 'all', all animation files depending on obs_ani, var_ani, com_ani, and pla_ani are made. But, this 'all' option requires a lot of memory.

• obs_ani
  Observation point number that is used for making the animation.

• var_ani
  Name of varialbe that is used for making the animation. 'e' and 'h' can be chosen.

• com_ani
  Name of component that is used for making the animation. 'x', 'y', 'z', and 'abs' can be chosen.

• pla_ani
  Name of plane that is used for making the animation. 'xy', 'yz', and 'xz' can be chosen.

• frame_speed_ani
  Time for 1 frame in the animation. The unit is millisecond.

• e_max_fig/e_min_fig
  Maximum/Minimum of the electric filed in the figure file.

• h_max_fig/h_min_fig
  Maximum/Minimum of the magnetic filed in the figure file.

• e_max_ani/e_min_ani
  Maximum/Minimum of the electric filed in the animation file.

• h_max_ani/h_min_ani
  Maximum/Minimum of the magnetic filed in the figure file.

• x_max_ani/x_min_ani
  Maximum/Minimum of the x axis in the figure file.

• y_max_ani/y_min_ani
  Maximum/Minimum of the y axis in the figure file.

• z_max_ani/z_min_ani
  Maximum/Minimum of the z axis in the figure file.
