HFSS15: Inserting Frequency Points

For Discrete sweeps, you can insert, change, or delete specific frequency points that you want to solve in the frequency range. They can be inserted individually to a new display, or to an existing display of uniform frequency points.

1. To pre-specify an initial uniform range of frequency points, use the Frequency setup of the Edit Sweep dialog to define the linear step, linear count, or log scale range you want, and click the Display button to list the count and frequency of those points as a table. For longer frequency tables, you can use a slider bar to scroll to through the complete list to see counts and values.

2. Select Single Points from the Type pull-down list.

The Frequency setup changes to single point mode. If you previously specified a range of frequency points, and clicked the Display button, the frequency table retains those points. This selection also enables the Insert button between the Frequency setup and the frequency table. The frequency points table now includes another column that contains a Save Field checkbox for each row.

Note that selecting a row highlights it and enables the Delete button under the Insert button. Clicking the cursor in the Frequency columns of the frequency points table makes their values editable.

3. In the Single text box, type a desired frequency point in the frequency units.

This enables the Insert and Change button.

4. Click Insert.

This inserts the new point in ascending order for the list and the count for each row adjusts. Clicking Change would replace the frequency value in the selected row.

5. Select the Save Fields column header if you want to save the calculated 3D field solutions associated with all port modes at that frequency. You can also select, or deselect the checkbox to specify individual frequencies.

6. Add or edit additional frequency points, and then click OK to save the sweep.

For Discrete sweeps, HFSS always solves the frequencies from highest to lowest.
