Abstract—The behavior of ferroelectric liquid crystals in an external electric field is simulated numerically.
The equations that describe the dynamics of the director of a liquid crystal are derived within the continuum
theory of elasticity with due regard for compressibility of smectic layers, finite anchoring energy, and dielectric
properties of orienting coatings and external elements of a real electric circuit. These equations make the basis
for simulation of the electrooptics of ferroelectric liquid crystals. The specific features and mechanisms of
thesurface-stabilized bistability and hysteresis-free electrooptical switching (the V-shape effect) are discussed.
