Input data for a full 3D 'evenly-divided disc'


A flat circular disc that is complete (that is, it does not have a hole at the centre) is divided into triangles that all have approximately the same area.


This is the recommended type of disc when there is no hole at the centre.


The specification is the same as for the ordinary disc except that there is only one radius and only one subdivision number.


All types of electrodes can be scaled and/or shifted and/or reflected and/or rotated.


If it is important for the edge of the disc to match the edge of a neighbouring electrode (for example a cylinder) then see note on matching electrodes.




For users who are editing or constructing an 'input data file' without the use of the data-builder -that is, pre-processor:

But Manual editing is certainly not recommended -it is a relic from the time when the databuilder was not available All users are strongly encouraged to use the databuilder, which always gives the correct formats and which has many options for which the formats are not described or easily deduced.


Typical data for an evenly divided disc, taken from shap3d03.dat, are:


edi evenly-divided disc

1. 0. 0. 0. radius, centre of disc

0. 0. 1. any other point on axis

1 1 numbers of 2 applied voltages (can be same)

25 number of subdivisions (0 cancels)
