“…On the other hand, the so‐called “validation” of a simulation is important for its use in technical applications like optimizing sintering schedules, compensating of costly distortions due to inhomogeneous density distributions after compacting, or the prediction of large pores or cracks. Successful work has been reported, for example, by German and colleagues, 64,65 by Olevsky and colleagues, 66–69 and particularly by Riedel and colleagues, 70–78 among others. Although simplifying assumptions on the geometry and the transport processes have been used, this approach was shown to be of high value in sintering technology.…”
