Sweeping a Variable in a Report

In SIwave, a swept variable is a variable that typically has more than one value. You can plot any calculated or derived quantity against one or more of the swept variable's values.

For large projects or projects with many variables, you may obtain faster post processing before generating a solution by selecting which variables function as Sweep variables. Only the variables with Sweep enabled are indexed for post processing.

To specify the swept variable values to plot a selected quantity against:

1. From the Report window , select the variable from the X (Primary Sweep) drop-down menu.
2. To modify the values that will be plotted for a variable:
   1. Click the [...] button on the X (Primary Sweep) line of the Report window to display a pop-up list of possible values.
   2. Select All Values or click the Edit button to display a window that lets you specify the sweeps to use.

All of the selected variable's values will be plotted.

To sweep values across a distance:

1. If you are plotting a field quantity along a line, define a polyline in the problem region.
2. From the Report window, click the line geometry of interest in the Geometry list.
3. Specify the quantities you want to plot along the axes.
4. For the X (Primary Sweep), select the Distance variable.

   The values at which the selected quantity or quantities will be plotted are listed to the right.

   By default, a post-processing polyline object is divided into 100 equally spaced points.

5. For Near field, to plot the selected quantity or quantities at every point on the line, select All Values, or clear All Values and select the point values on which you want to plot.
