I am preparing a Mathcad V15 computation for Electric Fields at given points across a power line corridor. Long ago I created one with a limited number of circuits (1) and wires (5) that processes correctly. The problem requires consideration of the effects of x energized wires at each point k in the corridor and time position b. The process is to compute charge and then electric field from each of x wires at each k over all b, sum over all x wires, then select the maximum values of EX and EY at each k. My early slim computation used brute force to eliminate the x dimension of wires. So I would create QM1 = QM[1 for the charge say and have a function QM1[b,k]. This requires creating a separate equation for each QM, one per wire. My programming effort is aimed at allowing variable input via a matrix and automatically processing the necessary equations to compute an answer. My problem is getting the new programs to work through the three variables. I attach my OK first slim document, a version of my new document and two pdf copies annotated for reference. Really I think all I need is some guidance on how to set up 3-dimensional problems with nested arrays and programs.
