Abstract Scope |
In recent years, metal additive manufacturing simulation capabilities in the SPPARKS microstructure simulation code have seen significant advancements. These include both refinements to physics models and computational capability improvements. Model improvements include the implementation of a finite-difference thermal conduction solver, material-dependent solidification behavior, and crystallographic texture prediction. Computational capability advancements include the ability to perform simulations on sub-volumes, utilize external thermal model results, and the implementation of novel heat sources, including a 3D spline-based melt pool and a jointed Rosenthal solution. Additionally, SPPARKS was recently migrated to a public GitHub repository to facilitate collaboration. This presentation will discuss these recent improvements, implications for AM process optimization, and future development plans. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525 |
