Abstract: A vertex model for the simulation of grain growth and grain boundary migration is developed and its implementation is explained in detail. The utilization of the model is also exemplified with different setups. In particular, the model was used to study the evolution of magnetically affected grain growth in samples with randomly oriented grains and the effect of the finite mobility of the boundary junctions on boundary migration. These examples emphasize the versatility of the model and illustrate its ample scope. The results of the simulations showed that a magnetic field can effectively affect the evolution of the grain growth kinetics and texture independently of the initial texture since the magnetic field will cause grains, with particular orientations, to have an advantage for their growth. As consequence, the sample will become strongly textured during grain growth. Theoretical considerations for the grain boundary migration with a finite mobility of the triple junctions were also reproduced and confirmed by means of computer simulation. The simulation results showed a very good agreement with the theoretical expectations.
