Title: A High-Performance Computing GPU Approach for Additive Manufacturing using MPM and Hedgehog

Purpose: The purpose of this project is to begin developing a physics-based high-performance computing (HPC) asynchronous-execution task-based simulation capability for modeling fundamental aspects of additive manufacturing using the Material Point Method (MPM). This project will extend the NIST-developed Hedgehog library with the goal of achieving near real-time simulation results.

Activities to be performed: The project builds on an existing simulation study and consists of three major tasks. Task 1 evolves the existing simulation to handle more complex physics of the laser sintering additive manufacturing process and model the physics of heating, melting, adhesion, and cooling of materials in the melt pool produced by the laser. Task 2 extends the physics model to handle keyhole cavity formulation. Task 3 compares simulation results with NIST-acquired images and refines the physics-based model to improve its fidelity; it also decomposes the code to target high-end compute systems with multiple GPUs per node.

Expected outcomes: The fundamental research supported by this grant will contribute to extending NIST Hedgehog so it can handle a wider range of problems and provide near real-time computational analysis. This research will also develop a physics-based simulation model targeting laser sintering additive manufacturing. The research supported by this grant will be presented in open scientific forums and published in the open scientific literature.

Intended beneficiaries: The high-performance computing (HPC) research community will be the general beneficiaries of this research. More particularly, this research directly contributes to approaches for the development of asynchronous many-task systems in HPC. Additionally, the physics-based models will contribute to a better understanding of laser sintering in additive manufacturing (AM) with the potential of improving process control in AM process.
