We are performing high-fidelity multiphysics simulations of laser-based additive manufacturing to study melt pool dynamics, interfacial mixing, and phase interactions in multimaterial builds. The simulations involve coupled heat transfer with phase change, laminar fluid flow, surface-driven Marangoni effects, and species transport. Due to the fine spatial resolution and the need to capture transient flow and thermal behaviour, each simulation generates a large volume of data, including 3D temperature fields, velocity vectors, and species concentrations over time. The requested storage will support multiple simulation campaigns, parametric studies, and long-term storage of both intermediate and final datasets for post-processing and analysis. Adequate storage is essential to enable checkpointing, visualization, and validation against experimental data, ensuring continuity and reproducibility of our research. The data will provide critical insights into melt pool behaviour and material mixing, contributing to the development of predictive models for process optimization in additive manufacturing.
