Input data for a simple flat rectangle.
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 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
(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) Either:
(a) The numbers n1 and n2 of subdivisions along the sides that connect the 1st and 2nd corners and 2nd and 3rd corners 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.
For important advice on subdividing please look at section 3.4 of the Users Guide or the general advice on segmentation.
The final number of segments, n1*n2, might be slightly different from N (so if greater control is required, use n1 and n2).
Note: If the initial rectangular subdivisions are subdivided again at a later stage by the program, say each into n parts, then the shortest and longest sides will be divided into n1 and n2 equal parts respectively to try to make the new subdivisions as square as possible, and n then becomes n1*n2, which in general is less than or equal to the starting value of n.
All types of electrodes can be scaled and/or shifted and/or reflected and/or rotated.
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:
rectangle
1.0 0.0 0.0 x,y,z of corners
1.0 0.0 1.0
1.0 1.0 1.0 | square lying in x = 1 plane, with ends of
1.0 1.0 0.0 | a diagonal at (y,z) = (0,0) and (1,1)
1 2 numbers of 2 applied voltages (can be same)
1. 0. z's at points of application of numbered voltages
8 8 number of subdivisions, sides 12 and 23 (0 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 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
(3) if nv1 and nv2 are different, then enter 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) Either:
(a) The numbers n1 and n2 of subdivisions along the sides that connect the 1st and 2nd corners and 2nd and 3rd corners 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).
