A Regular Difference Grid and Characteristics Method Math. Models Comput. Simul. Pub Date : 2023-12-01
Abstract An explicit characteristics method used to calculate the values of gas-dynamic parameters (GDP) of one-dimensional unsteady flows is considered. An algorithm for solving gas-dynamic equations written along characteristic directions is formulated for use on a regular grid. An example of calculating the problem for a cylindrical pipe is performed. It is shown that with a time integration step

Direct and Inverse Problems of Seismic Exploration of Anisotropic and Dispersive Elastic Media on Volume Integral Equations Math. Models Comput. Simul. Pub Date : 2023-11-04 P. N. Aleksandrov, V. N. Krizsky
Abstract The theory of seismic exploration is based on the theory of elasticity, where an important role is played by material equations: Hooke’s law. The equations of elasticity theory include the density of the medium. In the general case, at each point of the medium, it is necessary to determine a matrix of parameters with a dimensionality of 12 × 12 elements. In addition, these parameters can be
