Notes:
A 3D Vertex Model has been successfully implemented to investigate the evolution of aspecial grain assembly during grain growth. The model considers the mean curvature as drivingforce for the motion of the vertices and allows the consideration of all parameters affecting themotion of the system, i.e., grain boundary energy and line tension of the triple lines, as well as grainboundary (GB), triple line (TL) and quadruple point (QP) mobility as well. The used specialconfiguration makes it possible to study the influence of all structural elements of a grain boundarynetwork on the evolution of the system by allowing the steady-state motion of the boundaries of ashrinking grain. In the present work the different mobilities have been systematically varied and theevolution of the grain size with time has been studied as a function of TL and QP mobility. Theresults of the simulations are finally linked to the different kinetic regimes reached by the system
