Input data for a simple flat triangle.

The user specifies:

(1) the x,y,z coordinates of the corners

(2) the numbers nv1,nv2 that label the voltages that are applied to the triangle (the values of the voltages will be entered later) -nv1 and nv2 are the same if the triangle is an equipotential -they are different if a potential gradient is required in the z direction

(3) if nv1 and nv2 are different, then the user specifies the values of z at which these 2 voltages are applied (and these values of z can be outside the range of z of the triangle)

(4) the number n of subdivisions (which will be adjusted if not already in the form 2**m -that is, 1, 2, 4, 8, 16, etc).

For important advice on subdividing please look at section 3.4 of the Users Guide or the general advice on segmentation.

When the number of subdivisions is 2**m the triangle is subdivided in m stages and at each stage the longest side is bisected.

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 a triangle on a flat surface, taken from shap3d13, are:

triangle

0.0774 0.0 0. x,y,z, of corners

-0.1547 0.0 0.

0.0774 0.1340 0.

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

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

The data required are:

(1) x,y,z coordinates of corners

(2) numbers nv1,nv2 that label voltages that are applied to the triangle

(3) if nv1 and nv2 are different, then enter values of z at which these 2 voltages are applied

(4) number n of subdivisions.
