摘要：
This paper describes the development of a multiphysics welding simulation model based on the discontinuous Galerkin (DG) finite-element method. Our numerical model implements a classical enthalpy-porosity constitutive law accounting for hydrodynamic and thermal effects occurring during the phase transition from solid to liquid metal. The objective of the study is to present the verification of our numerical framework and explore the applicability of the DG formulation to the simulation of welding processes. Three computational examples of increasing complexity are presented.
