FDTD Results

In the FDTD Result section, users can select FDTD simulation results for visualization and create new custom datasets. Plotting options are also available to enhance data visualization. After the simulation is complete, click Post-Run Result button to open the Result panel.

Dataset

Users can select monitor datasets for visualization in this result section and also create new custom datasets.

Monitor Dataset

All the monitors included in the simulation are listed here in a three-like structure. Users can navigate through them and select the information they want to plot.

Custom Dataset

Allow the users to create custom datasets based on the monitor results. Click the Add Custom Dataset button to open the Dataset Editor panel.

Coordinate

In this result section, users can filter dataset data. Depending on the monitor type and settings, one or more of the following fields are available: frequency, time, position, direction, and mode index.

Plotting Setting

In this result section, users can adjust the dataset plotting setting to customize the visualization.

1D Dataset

Line Type: Line type selection.

Options:

• Solid (Default)
• Dash
• Dot
• Dash Dot
• Long Dash
• Long Dash Dot

Line Width: Line width edit. Directly edit the line width value or use the up and down arrows to change its value.

Type: floating-point number

• Constraint: greater than 1
• Default: 1

X Axis: When Auto range is True users can automatically adjust the x-axis limits. To customize the axis limits, set Auto range to False and enter the minimum and maximum limit values in the min and max edit boxes.

Y Axis: When Auto range is True users can automatically adjust the y-axis limits. To customize the axis limits, set Auto range to False and enter the minimum and maximum limit values in the min and max edit boxes.

2D Dataset

In this result section, users can adjust the plotting setting of 2D datasets.

Use equal aspect ratio: When True, the same data scaling is used to plot units for x- and y-directions.

Overlay with structure: When True, plots the permittivity distribution over the fields and let the user to adjust it between fully opaque (1) and fully transparent (0).

Color Scale: Set the color bar minimum and maximum limits.

Animation

This feature allows users to create animations and/or apply a phase shift to FieldMonitor Real or Imaginary field datasets.

Phase: Select a phase shift to apply to instantaneous field amplitude.

Type: floating-point number

• Unit: degree
• Default: 0

Animate: Start or pause an animation.

Setting: Animation set up.

Export: Export the animation to a GIF file.

Animation Setting

Animation set up. Click the Setting button to open this panel.

Phase: Select an initial phase shift to apply to instantaneous field amplitude.

Type: floating-point number

• Unit: degree
• Default: 0

Number of Steps: Number of sampling steps in one animation cycle.

Options:

• 16
• 32 (Default)
• 64

Animation Rate: Animation frames per second. Use the slide bar to choose between 30 and 60 frames per second.

Note: Animations are created by calculating the instantaneous field amplitude ($E(\phi)$) using the following equation:

$E(\phi)=E_{DFT} \cdot e^{j\phi}$

where $\phi$ is the phase value in radians $[0, 2\pi]$.
