We have proposed an electron dynamics simulation method based on the Vlasov equation, which can be applied to non-equilibrium states before thermalization and does not need to refer to experimental data, and has been validated for bulk aluminum. In this study, we have extended the program to evaluate the amount of energy injection according to the depth from the surface with surface processing, and benchmark tests were conducted.
