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.
