Programs

ESModelBuilder is a simple program to visualise the electric field and potential from any small set of point charges in 3-D space. The fields can be visualised as field lines or as vector field (hedgehog) plots and the potentials as translucent surfaces. The resulting visulalisations can be rotated in real time on a PC with a reasonably modern video card.

The program and some example files are found in a zip file here. Right click on the link and select Save Target As to download the file to your machine. Then right-click on the zip file and select Expand to expand it into a normal folder. ESModeller has to be opened as an application; you cannot drag and drop files onto it.
