Terry Fritz's Tesla-Coil E-Field Simulator:  E-Tesla6
The inputfile fields ar filled, as far as making sense, from the data Large files for potential (voutput.xls) and field-stress (soutput.xls) are available
within the "TC calc." sheet. - "Result C" is fed back to sheet "TC calc."   but it is recommended to handle/view them externally from this workbook.
