Abstract Scope |
Laser powder bed fusion (LPBF) is a common form of metal additive manufacturing capable of rapidly producing complex specialized parts. Currently, the unique microstructures produced by LPBF are studied through a combination of experimental and computational studies. However, these studies are limited to small length scales as microstructures of large parts are expensive both physically to image and computationally to simulate. This work opens the door for much cheaper, large-scale LPBF simulations through the integration of microstructure-based models and domain “stitching” capabilities. This work provides a means to divide the computational work of LPBF simulations into multiple subdomains and predict the resultant microstructure with reduced memory usage and improved parallel performance. The “stitch” technique allows for simulating the microstructure of large LPBF parts, which are otherwise unreasonable to model.
