Effect of Laser-Matter Interaction on Molten Pool Flow and Keyhole Dynamics (2019, methodology): “In the more recent multiphysics modeling of keyhole dynamics [27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39], the ray tracing model is coupled with a computational thermofluidic dynamics model and a free surface tracking model (based on level-set, volume-of-fluid, or arbitrary Lagrangian-Euleri”
