摘要: A number of problems on the laser radiation propagation and absorption are stated Maxwell's equation base for simulation treatment materials, namely cutting, welding, drilling metals, selective melting sintering powders. The algorithm numerical solution equations by finite difference time domain method is employed with parallelizing elements; peculiarities setting some boundary conditions interaction isotropic media analyzed.
