Supplementary Material to "An improved grand-potential phase-field model of solid-state sintering for many particles"

Supplementary Material to the publication "An improved grand-potential phase-field model of solid-state sintering for many particles" by Seiz, Hierl and Nestler. This contains the pre-study for determining the effective stiffness for the rigid-body velocity calculation and video files showing the 3D evolution of the green body in more detail than possible in the paper itself. slicethru_{start,end}.webm: Moving slices through the 400^3 nm green body at t=0.045ms and t=1.8ms representing the start and end of the simulation respectively. White/transparency indicates the surrounding vapor, with the colourmap showing different grains. Any interfaces are shown as black lines. greenbody_400.webm : Time evolution of the 400^3 nm green body based on the solid-vapor interface. White/transparent indicates the surrounding vapor, with the brownish material indicating the grains. prestudy.zip: Contains the notebook and data used for the pre-study for determining the effective stiffness. A binder is available at https://mybinder.org/v2/git/https%3A%2F%2Fgit.scc.kit.edu%2Fxt5201%2Fsupplementary-material-for-improved-pf-sintering-model/master?labpath=eval-kvar.ipynbThe research was funded by the Deutsche Forschungsgemeinschaft under grant number NE 822/31-1, with most of the simulations being performed on the HAWK supercomputer at the High Performance Computing Center Stuttgart. The parallelization and code optimization were funded via by KNMFi within the programme MSE (P3T1) no. 43.31.01
