Global Definitions - Parameters
It is good modeling practice to gather constants and parameters in one place so that you can change them easily. Using parameters will also improve the readability of your input data.
The following parameters will be defined: the overvoltage amplitude
Vi
, thickness of the grading ring
H
, diameter of the grading ring
D
and distance to the grading ring from the end
d
.
