Input data for an end disc triangle.


An end triangle on a disc (that is, a triangle that lies on the edge of a disc -the outer edge or inner edge if there is a hole at the centre of the disc).

If this triangle is further subdivided by the program then the selected side of the triangle continues to lie on the circular edge. The other two sides of the triangle will lie on straight lines after subdivision.


The specification is the same as for the simple triangle, except that the x, y and z coordinates of the centre of the bounding circle are required. The first 2 corners define the side that lies on the bounding circle.


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


Examples of all the different types of triangles are given in shap3d28.dat.



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 end (that is, edge) triangle on a disc, taken from cpo3d.dat, are:


edt -end disc triangle

100. 0. 50. corners

70.71 70.71 50. (1st 2 corners are on bounding circle)

0. 0. 50.

0. 0. 50. centre of end bounding circle

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

0 number of subdivisions (=2**n) (0 cancels)


(and note that this electrode has been 'cancelled' by the last line).
