xnec2c is a GUI interactive application that (in its current form) reads NEC2
input files but presents output data in graphical form, e.g. as wire frame
drawings of the radiation pattern or near E/H field, graphs of maximum gain,
input impedance, vswr etc against frequency and simple rendering of the antenna
structure, including color code representation of currents or charge densities.
These results are only calculated and drawn on user demand via menu items or
buttons, e.g. xnec2c is interactive and does not execute NEC2 "commands" in
batch style as the original does.
