    Preferences

    The Preferences window in AN-SOF allows you to customize the unit system for input data, adjust the workspace appearance, and configure various default software settings.

    To access Preferences, go to the main menu and select Tools > Preferences (or click the gear icon on the toolbar).

    Units

    On the Units tab of the Preferences dialog box (Fig. 1), you can select suitable units for frequencies, lengths, wire cross-sections, inductances, and capacitances. In addition to standard SI units, options such as inches (in) and feet (ft) are available for lengths and cross-sections.

    Fig. 1: Units tab in the Preferences dialog box where frequencies, lengths, wire cross-sections, inductances, and capacitances can be set.

    Workspace

    On the Workspace tab (Fig. 2), you can toggle the workspace background color between black and white. You can also select from three line-thickness levels (Thin, Medium, and Thick) for rendering objects in the workspace, including axes, wires, and wire grids.

    Additionally, you can customize the scale and color of source and load symbols, or check Show Wire Segments to display individual wire segments directly in the 3D workspace.

    Plots

    On the Plots tab of the Preferences dialog box (Fig. 3), you can set the scales and ranges for the graphs displayed in the main Plots tab.

    The main Plots tab contains four graphs plotted as a function of frequency: Impedance, VSWR/S11, Gain, and Front-to-Rear (F/R) & Front-to-Back (F/B) ratios. Frequency forms the horizontal axis for all four plots.

    To customize an axis scale, use the following options:

    • Auto: Check this option to let AN-SOF adjust the axis scale automatically. Uncheck it to enter values manually for Min (minimum value), Inc. (increment), and Max (maximum value). Set Inc. to zero to let the software calculate the increment automatically.
    • Log: Check this option to apply a logarithmic scale to the selected axis.

    Options

    On the Options tab (Fig. 4), you can enable or disable the following settings:

    • Display main toolbar: Displays the main toolbar.
    • Confirm wire deletion: Displays a confirmation dialog box before deleting any wire.
    • Confirm simulation abort: Displays a confirmation dialog box before aborting an ongoing simulation.
    • Include H-field in “All Metrics” calculation: Calculates the near magnetic field (H-field) when you click Run All Metrics.
    • Close active charts on exit: Closes all active chart windows automatically when you exit AN-SOF.
    • Auto-close solver progress window: Closes the solver progress window immediately after a calculation completes.
    • Significant Digits in Tables: Sets the number of significant digits displayed in result tables. This setting affects data presentation only and does not alter the double-precision calculations used by internal algorithms.

    📝 Note

    All preferences can be configured at any time, either before or after performing a calculation.
