From the developer:
This free educational utility is a 2d boundary element method field solver. It allows you to view the equipotential lines around a transmission line. By seeing where the lines are densest you can view the areas of strongest field and better understand which areas of a structure have a greater effect on impedance.
You may want to check out more software, such as Live DXF2BMP or CAD To DMC, which might be similar to EPD100.
