Additional difficulty consists in lack of data on materials properties at the temperatures superior to their melting point. The present work summarizes the numerical challenges in creation and validation of free-surface models using ALE moving mesh coupled with heat transfer equation and Navier-Stokes fluid flow. %G English %2 https://hal.science/hal-01962642/document %2 https://hal.science/hal-01962642/file/Conf_Bendaoud_al_Comsol_2018.pdf %L hal-01962642 %U https://hal.science/hal-01962642 %~ UNIV-BOURGOGNE %~ CNRS %~ UNIV-BM %~ LMGC %~ ICB %~ UNIV-BM-THESE %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
