In this thesis, three separate numerical methods for the simulation of Laser Beam Melting (LBM) are developed or adapted, respectively. The PXFEM supplements the function space in areas of high gradients with parameterized enrichment functions to allow for the representation of steep local gradients with few degrees of freedom. The LBM-MM dynamically partitions the system of equations into components with local time steps, taking into account the layers to be added by the buildup process. The LBM-DSS linearizes the system of equations and the information from the previous solution step is adopted completely or partially.
