Preferences include the unit system to be used for showing input and output data, the workspace appearance, and several miscellaneous options. Preferences can be accessed via Tools > Preferences from the main menu. A suitable unit for frequencies, lengths, wire cross-section, inductances and capacitances can be selected in the Units page of the Preferences dialog box, Fig. 1. In the cases of lengths and cross-section, inches (in) and feet (ft) can be chosen apart from the standard SI units.
The workspace background color can be switched between black and white in the Workspace tab, Fig. 2. Also, there are three levels for the pen width used to draw objects on the workspace: Thin, Medium, and Thick. The pen width option applies to axes, wires, and wire grids. The size of the source symbol can also be edited as well as its color and the color of loads. Check the Show Segments option to display the segments in the workspace.
In the Options tab, check the Show Main Toolbar option to see this toolbar, Fig. 3. Two “Ask before…” questions can be set to avoid mistakes. If the option “Run ALL” also calculates the H-Field is checked, the near H-field will also be calculated after clicking on the “Run ALL” button. Here you can also choose to close the chart windows after exiting AN-SOF. Select the option “The comma is set as the decimal symbol” if you use the comma as decimal separator in your Windows(R) regional settings. The number of significant digits shown in results can also be set (this option does not modify the double precision used in the internal algorithms).
All the preferences can be configured at any time, either before or after performing a calculation.
