[ESPResSo-users] magnetic field due to magnetic dipoles

Dear all,
I am a new user of Espresso and I would have a question
for more experienced users. I read the documentation (user's guide) but
couldn't find the answer.
I would like to simulate a system of
magnetic dipoles. As far as I understood, Espresso is able to calculate
the energy of such a system and forces acting on each particle.
In my case I would like to know what is the magnetic field (due to
all other dipoles) at the position of each particle. Problem is not so
trivial, since the magnetic field due to magnetic dipole decreases as
1/r**3 and one should take into account contribution from all particles
(for beginning I assume repeating cells in x and y axis).
Previously I studied simpler systems and I know that magnetic field due to other dipoles may increase magnetic moments by 20%.
My question is: is there any way to obtain the magnetic field due to magnetic dipoles from Espresso?
