8th 'shape' file for CPO2D, thick cylinder with rounded edge
There are 3 electrodes that represent one of the edges of a thick cylinder.
The first is the inner wall of the thick cylinder, radius 1, from z = -1 to z = 0.
The second is the rounded edge, radius 0.05.
The third is a disc for the flat end, inner radius 1.05, outer radius 1.3, at z = 0.05.
The segments of the first and second electrodes have been concentrated at
the ends near to the corner, using the 'advanced' option to set the exponent p.
These concentrations are important because they ensure that the widths of
the segments near the edge are comparable with those of the edge.
To see the distribution of segments use the option to 'create gaps between segments'.
Unfortunately this comparability might be difficult to achieve in a practical
case because the edge would usually be sharper than in the present example.
Increasing the exponent p can help, but it might be necessary to do something
that is usually strongly discouraged.
This is to disable the tests for nearness of segments, using
databuilder\segments\advanced options\disable check for overlapping...
Violating the usual rules in this way should not be harmful because the segments
all have the same potential and the system has axial symmetry.
