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.

bend_angle
Port 1
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 - 90o every 10o.

To view a port or boundary, select the desired item in the Project Tree. It is then highlighted in the Model
window and the properties will be displayed in the Properties window. Selecting an object in the History tree
will also display its properties.
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.
