There is presented new approach to dynamical simulation of linear and nonlinear electrodynamical processes coupled with laser-induced heating through temperature-dependent absorption and refraction. That approach is similar to finite-difference time-domain technique. Mathematical model and idea of developed code for the simulation are presented. Among calculation problems there are discussed boundary conditions for transparent boundaries of calculation grid and influence of space resolution. There are considered several applications of the code, in particular investigation of laser-induced modification of dielectric surface by femtosecond pulses, investigation of laser-induced processes in dielectric films with inhomogeneous microstructure. Perspectives of developing of 3D simulation code as well as including of thermomechanical, chemical and other processes into the developed model and code are discussed.
