| Abstract: | We study formation and development of laser-induced heating,melting and evaporating process during laser-matter interaction. Local adaptive mesh refine method in two-dimensional structured code is adopted as soon as material evaporates along the direction of laser. Wilkins method and finite volume diffusion scheme based on reconstruction of values on vertex are adopted to handle momentum equations and energy equation. |
