MeltPoolDG is an open-source, research-driven simulation software for high-fidelity metal additive manufacturing. It predicts the coupled powder–melt–gas dynamics occurring in processes such as laser powder bed fusion (LPBF) and binder jetting, aiming for the detailed simulations of melting, solidification, evaporation, recoil pressure, capillary effects, powder transport, and multiphase thermo-fluid–structure-contact interactions.
MeltPoolDG is developed as part of the Professorship of Simulation for Additive Manufacturing (SAM) at the Technical University of Munich (TUM), with a focus on application-oriented, cutting edge simulation methods for metal additive manufacturing.
- High-fidelity multiphase thermo-fluid simulations for metal additive manufacturing
- Continuous and discontinuous Galerkin finite element methods (CG/DG FEM)
- Conservative level-set methods with CutFEM immersed-interface techniques
- Discrete element methods (DEM) for powder particle dynamics
- Matrix-free operator evaluation with SIMD vectorization
- Distributed-memory parallelization using MPI
- Adaptive mesh refinement
- Designed for application-oriented research and large-scale HPC simulations
