?How to define the "fill factor" for each coil?
You have to multiply the conductivity of the bulk coil material by the
fill factory and enter that value as the conductivity for a wound
region. This is still sort of a kludge--I'm planning to put in a
parameter for wire gauge so that the program will figure out the fill
factor itself based on the wire size and number of turns.
?Are both coils in serie, oder is a coil as the "PRIMARY" and

the "SECUNDARY" a Transformator?

For this particular example, both coils are connected together in series
(i.e. not like your typical transformer). I did this because this is
sort of a benchmark problem, and that's the way that the benchmark was
connected. See http://ee.ascs3.uakron.edu/team/problems/problem28.pdf
Although FEMM doesn't solve the transient simulation described in the
TEAM writeup, one can compare the final steady-state position reported
in the writeup with a FEMM simulation.
