Аннотация: Based on the mathematical model describing the thermomechanical behavior of a liquid crystal, which takes into account the couple-stress interactions, the system of two differential equations for tangential stress and angular velocity was obtained in two-dimensional case. Computational algorithm for numerical solution of this system of equations of the second order under given initial data and boundary conditions is worked out. The algorithm is implemented as a parallel program in the C language using the CUDA technology for computer systems with graphic accelerators. A series of numerical computations of acoustical waves in a liquid crystal was carried out to demonstrate the efficiency of proposed parallel program.
