[ESPResSo] Coulomb interactions 1D 3D

[Ivo Kabadshow]

Dear all,

 I have questions concerning the sample input data mmm1d_system.data.

1.)
What is the effect of the "box_l" parameter on the particle coordinates?

I would assume that all particles have to be enclosed in the 
simulation-box (box_l box_l box_l). But the file holds particles with 
coordinates larger than l_box.

2.)
What is the purpose of the first two particles with charge 0.0?

3.)
What is the influence of the p3m parameter "cao"? I couldn't find any 
information.

Many thanks in advance

 Ivo Kabadshow
