Hi,

The program E-Tesla6 generated an array 500 x 500 that represents all the 
voltages (or field stress in this case) around a Tesla coil:

Here is the input file I used.  You might want to reduce the grid size to 
say 100 instead of 500 at first since 500 takes time to calculate.

MathCad simply displayed this array as a contour plot in greyscale.

You will have to use file association in the first menu to change the file 
name/location for your situation.  E-Tesla generates an array called 
"soutput.xls" which is simply the array.

E-Tesla sort of explains it in the help file.

Cheers,

        Terry
