Input data for a simple flat rectangle in the x, y or z planes.

A rectangle that lies in a plane x = constant, or y = constant, or z = constant.

The user specifies:

(1) the coordinate of the x, y or z plane

(2) the coordinates (for the other two axes, in cyclic order) of any two opposite corners, in the given plane (that is, for the x plane the y and z coordinates of the corners are needed, while for the y plane the z and x coordinates are needed and for the z plane the x and y coordinates)

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

(4) if nv1 and nv2 are different, then the user specifies the values of z at which these 2 voltages are applied

(5) Either:

(a) The numbers n1 and n2 of subdivisions along the 2nd and 3rd directions, in cyclic order (that is, for a constant coordinate x or y or z the 2nd and 3rd directions are y,z or z,x or x,y respectively)

Or (the usual recommended choice):

(b) The total number N of segments and 0. The 0 will trigger the program to partition N into n1 and n2 in such a way that all the rectangles are as nearly square as possible. The final number of segments, n1*n2, might be slightly different from N (so if greater control is required, use n1 and n2).

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

These 3 types of electrodes can be scaled and/or shifted and/or reflected and/or rotated (but to carry out a rotation the program has to convert them to the full rectangular type).

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 simple flat rectangle, taken from test3d03, are:

rex rectangle, x=constant

1.0 value of the x coordinate

0.0 0.0 y and z coordinates of end of a diagonal

1.0 1.0 y and z coordinaes of the other end of same diagonal

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

1. 0. z's at points of application of numbered voltages

8 8 total number of subdivisions and 0, or divisions in the y and z directions

The data required are:

(1) coordinate of x, y or z plane (for rex, rey and rez respectively)

(2) coordinates (for the other two axes, in cyclic order) of any two opposite corners, in the given plane

(3) numbers nv1,nv2 that label voltages that are applied to the rectangle

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

(5) Either:

(a) The numbers n1 and n2 of subdivisions along the 2nd and 3rd directions, in cyclic order (that is, for a constant coordinate x or y or z the 2nd and 3rd directions are y,z or z,x or x,y respectively)

Or (the usual recommended choice):

(b) The total number N of segments and 0. The 0 will trigger the program to partition N into n1 and n2 in such a way that all the rectangles are as nearly square as possible. The final number of segments, n1*n2, might be slightly different from N (so if greater control is required, use n1 and n2).
