Abstract: Numerical solutions to magnetoelasticity equations are considered. A numerical scheme based on central differences for spatial derivatives and the fourth-order Runge–Kutta method for time derivatives is used. The initial data is a solitary wave and a smoothed step (Riemann problem). The study is carried out beginning with simpler equations and continues for more complex ones. New types of discontinuity structures are found, and the conditions for the correctness of the equations are investigated.

Key words: micropolar medium, solitary waves, discontinuity structures, finite difference methods.
