Here are a number of examples of using atlc. Most of the example files can be found in the examples directory or if atlc is installed on the system, they will normally be located at /usr/local/share/atlc/examples. The very largest files, are not distributed to save disk space.

The full details of exactly what the files mean is given here.

In the case of the open structures (such as microstrip or twin-wire cables) the electric field extends to infinity, as there is no surrounding conductor like in the case of the coax, u-shaped conductor of the very odd shape. By putting an open structure onto a finite grid, which does not extend to infintiy, we have introduced an error. You should check that the electric field in the file of such structures is zero close to the edges - if not, a significant error will be introduced.
