Field Map Generator

Calculates and plots the time average of amplitude and phase of an XFDTD simulation and saves this data

Input:

  • leader label: name of XFDTD simulation
  • section label: observation plane of steady state data
  • initial file: beginning time step of steady state data
  • last file: end time step of data
  • skip: time increment of steps
  • number of rows: number of cells in x direction for xy and xz planes
    • number of cells in y direction for yz plane
  • number of columns: number of cells in y direction for xy plane
    • number of cells in z direction for xz and yz
  • frequency: frequency of voltage source
  • time_step: calculated by xfdtd (lookup in fdtd.diag)
  • load_path: full path of the converted data
  • save directory: where you want to save the amplitude and phase profile of the converted data for x, y, and z components of the voltage source

Buttons:

  • Save as Default: Saves the current input values so you don’t have to re-input them the next time you use this panel
  • Calculate: Runs the calculation program

Example:

This is the directory where the output from the Convert XFDTD to Optiscan calculator is stored

converted_dir

This is what I input into the panel

field_map_panel

  • leader label is “symmetric152020”
  • section label: xy plane at z=21
  • my first time step is 878 and my ending time step is 1000
  • the skip is 2
  • I have 41 rows and 41 columns in my simulation
  • frequency and time step I copied from the xfdtd.diag file that is automatically saved into the directory with my xfdtd simulation data (see below)
  • the output from the Convert XFDTD to Optiscan calculator is stored in c:\converted_symmetric152020\
  • I want the output saved in “c:\temp\” (note the ending slash)

This is where my XFDTD simulation output is stored (notice the fdtd.diag file) :

fdtd_dir

This is the contents of the fdtd.diag file:

fdtddiag

Output:

  • file: the time averaged complex amplitude and phase values are saved in a matlab file that has a name that is made up of the name of the simulation and the section label with an extension of “.mat”
  • plot: plot of the period of the wave
  • period
  • field profile of amplitude and phase
  • profile
