Abstract Scope |
Phase-field is now a standard approach for modeling solidification fronts. When used in the context of additive manufacturing, computational requirements can be quite demanding in 3D, with many grains of different orientations, multiple alloying species, and high velocity moving solidification fronts. The addition of a coupled evolving temperature field can make the equations very stiff, in which case an implicit time stepping approach can be beneficial. In this talk, we will discuss some of these issues, and how recent developments in high-performance computers with GPU accelerators provide both challenges and opportunities for these models. More specifically, we will discuss and show results using the Kim-Kim-Suzuki model of coexistent phases coupled with CALPHAD databases.
