Abstract
An algorithm for the solution of a moving boundary problem with two mo ving interfaces describing pulsed-laser heating of metals and semicond uctors is presented. Contrary to dir: standard Stefan-type models. mel ting and evaporation due to laser irradiation are treated as: nonequil ibrium processes. Computational implementation of the model is discuss ed and results of numerical experiments :ire given. The significance o f various boundary conditions in modeling fast processes is tested and the effect of including evaporation into the model is discussed. (C) 1997 Elsevier Science B.V.
