HFSS15: Parametric Sweep of a Coax Bend

Description - This is a model of an air-filled coax bend. Two teflon supports with inner radius compensation are included in the model. The variable here is bend_angle and it controls the angle of the top half of the bend.

Model - The walls of the coax use the default outer PerfE boundary. The inner conductor is copper. The ports are assigned to the faces of the coax so port2 will automatically move with the coax body as the angle is changed.

Setup - Adapt at 5 GHz and do an interpolating sweep from 0.1 to 5 GHz. The defined Parametric sweep in bend angle sweeps from 50 - 90^o every 10^o.

Post Processing Coax Bend

After solving, you can view solution data by right-clicking on Setup1 and selecting Profile to display the Solution dialog. You also view the Solution tabs for Convergence, Matrix Data, and Mesh Statistics. To view the solution data for different bend angle values, click on the ellipsis [...] net to the design variation box and select the variation of interest.

To view the S Parameter frequency plots for all five bend_angle variations, double-click on XY Plot 1 under Results in the Project tree.

To see the shade plots of the electric field, double-click on Mag_E1 under Field Overlays>E Field. To view all variations right-click on Mag_E1 and select Animate. In the Select Animation window select New, and then select bend_angle for the swept variable in the setup pane. Then click OK.
