Abstract
The paper presents a technique for simulating the laser-matter interaction. The technique is based on a single-temperature plasma model and includes schemes for solving three-dimensional gas dynamics equations, a nonlinear heat equation, and a method for calculating the thermal contribution of laser radiation by tracing rays through a computational grid. The schemes are implemented using the technology of local adaptation of computational grids of the octree type. Results of three-dimensional simulation of the effect of a high-power nanosecond laser pulse on a layer of cryogenic hydrogen are presented.
