Using the Hawk supercomputer at the High-Performance Computing Center Stuttgart (HLRS) a research team led by Prof. Britta Nestler at the Karlsruhe Institute of Technology has been running cutting-edge phase-field simulations of sintering—a process using heat to fuse together materials from a loose powder packing. The so-called phase-field computational approach allows the researchers to simulate individual particle interactions during this process, representing them as they morph and shift phases, sizes, or other attributes. The team was able to make significant improvements in its modelling approach, and has further plans to refine its application to better account for local densification of the material. The team published its results in Modelling and Simulation in Materials Science and Engineering.
