Plotting the Current Distribution

3D Plots

To visualize how current flows across your entire model, navigate to Results > Current Distribution 3D in the main menu. This command launches the AN-3D Pattern application, which renders the current amplitude directly on the 3D structure using a dynamic color scale (Fig. 1).

Beyond amplitude, you can also analyze the complex components of the current. By selecting the Plot menu within AN-3D Pattern, you can display:

  • Amplitude
  • Phase
  • Real part
  • Imaginary part

Adjusting the Color Bar in AN-3D Pattern

For precise data interpretation and professional presentations, you can manually override the automatic scaling. This allows you to set specific increments (e.g., multiples of 5).

  • Navigate to Edit > Preferences in the AN-3D Pattern menu (Fig. 2).
  • Manually define the Max and Min values of the color scale to highlight specific ranges of interest.

2D Plots

If you need to analyze the current along a specific wire in detail, you can generate a Cartesian plot using AN-XY Chart.

Method 1: Quick Access

Right-click directly on a wire in the workspace and select Current Profile 2D… from the pop-up menu (Fig. 3).

Method 2: Toolbar Selection

  1. Click the Pick Tool button (arrow icon) on the toolbar.
  2. Left-click the desired wire.
  3. Go to Results > Current Profile 2D… in the main menu.

Within the AN-XY Chart interface, you can toggle between amplitude, phase, and complex parts via the View menu.

💡 Tips

To optimize your analysis of 2D current distributions, AN-XY Chart provides several interactive navigation and data management features:

  • Zooming: To focus on a specific area of the plot, press and hold the left mouse button while expanding a box over the desired region.
  • Panning: To move the view without changing the zoom level, right-click on the graph and drag the mouse.
  • Reset View: To quickly return to the original full-scale view, left-click and expand a small rectangle in an upward direction anywhere on the plot.
  • Units and Scale: Go to Edit > Preferences (or click the gear icon on the toolbar) to change the units of plotted magnitudes or customize the scales and ranges of the horizontal and vertical axes.
  • Data Export: Go to File > Export to export the raw plot data to a CSV or TXT file.
