Description
|
The goal is to generate a uniform deflection field Ex in a cylindrical pipe. The solution is to divide the pipe into a number of wedge sections with voltages proportional to cos(theta). The calculation investigates the quality of the field approximation as a function of the number of wedges, N.

Results
|
The top illustration show the mesh geometry for N = 12. The middle illustration compares contours of potential for N = 2 and N = 12. The lower illustration shows contours of Ex in the range 90.0 V/m to 110.0 V/m as a function of N. The theoretical value for an infinite number of wedges is 100.0 V/m.
