We calculate the effects of Lense–Thirring precession on the inner regions of an accretion disc by solving the equations governing the tilt of a twisted, viscous disc derived by Papaloizou and Pringle. We confirm the earlier conclusion of Bardeen and Petterson that the rotation in the inner regions of the disc aligns with the spin of the hole. We find, however, that previous estimates of the radius at which this alignment occurs are incorrect.
