Abstract

The problem of simulation of thermal processes in laser irradiation on the surface of various materials is discussed, in which uses a new approach based on the solution of integral equations of heat transfer. For aims of describing the physical characteristics and geometry of the model authors use the principles of the cluster model, implemented in the software package CLUSTER2D. Article describes the features of software to create thermophysical model for numerical calculations. This approach helps to avoid oscillations in the resulting numerical solutions, which arise when applying the finite-difference and finite-element methods.

Keywords:
