Physics-based preconditioning for stiff multi-physics problems in additive manufacturing processes

PhD Candidate
2013-2017

I develop computer algorithms that solve the mathematical equations corresponding to the motion of a fluid (a liquid or a gas). Specifically, my research is in the field of computational fluid dynamics (CFD) and is at the cross-section between applied mathematics, computer science, and physics/engineering. My current application of interest modeling the physics of a metal 3D printing process, known as selective laser melting (SLM). Simulating the physics of this process is a challenging inter-disciplinary problem involving multi-physics (fluid dynamics, heat transfer, phase change, laser physics). My research involves speeding up the mathematical computations of a recently developed compressible flow solver in the ALE3D multi-physics code. I’m particularly focused on developing physics-based preconditioners for highly stiff numerical systems, enabling multi-physics codes to scale to thousands of processor cores.

I am conducting my research full-time in the Design Physics Division at the Lawrence Livermore National Laboratory in Livermore, CA.
