The variable capacitor example demonstrates the parameter sweep feature in combination with the capacitance calculation of the electrostatic solver.
The structure comprises the fixed plates of the capacitor and the variable plates with insulating material which are attached to a rotating wheel.
The default solver settings provided by the electrostatic template are not changed here. To perform electrostatic calculations a potential value of 1V is defined at the rotating part and of 0V at the fixed plates of the capacitor.
Potential definitions on the capacitor.
The rotation angle "alpha" is considered for a variation between 0 and 90 degree using the parameter sweep feature. The capacitance matrix is monitored during the parameter sweep run.

By selecting a capacitance table (grounded values)
in the navigation tree, one can study the influence of the rotation angle
"alpha" on the capacitance values. In addition the parameter
view offers a lot of options to create plots afterwards: Post Processing:
