  A very important issue in the area of galactic dynamics is the detection of
chaotic and ordered motion inside galaxies. In order to achieve this target, we
use the Smaller ALignment Index (SALI) method, which is a very suitable tool
for this kind of problems. Here, we apply this index to 3D barred galaxy
potentials and we present some results on the chaotic behavior of the model
when its main parameters vary.
