  We investigate the flow of material from highly misaligned and polar
circumbinary discs that feed the formation of circumstellar discs around each
binary component. With three-dimensional hydrodynamic simulations we consider
equal mass binaries with low eccentricity. We also simulate inclined test
particles and highly-misaligned circumstellar discs around one binary component
for comparison. During Kozai-Lidov (KL) cycles, the circumstellar disc
structure is altered through exchanges of disc eccentricity with disc tilt.
Highly inclined circumstellar discs and test particles around individual binary
components can experience very strong KL oscillations. The continuous accretion
of highly misaligned material from the circumbinary disc allows the KL
oscillations of circumstellar discs to be long-lived. In this process, the
circumbinary material is continuously delivered with a high inclination to the
lower inclination circumstellar discs. We find that the simulation resolution
is important for modeling the longevity of the KL oscillations. An initially
polar circumbinary disc forms nearly polar, circumstellar discs that undergo KL
cycles. The gas steams accreting onto the polar circumstellar discs vary in
tilt during each binary orbital period, which determines how much material is
accreted onto the discs. The long-lived KL cycles in polar circumstellar discs
may lead to the formation of polar S-type planets in binary star systems.
