Príklady coarsening

• This is because grid geometries can be highly irregular, thus allowing only a modest amount of coarsening.

• In rare cases, a gradual coarsening-upwards trend is also observed.

• In fact, this phenomenon should rather be interpreted as 'mesh coarsening' away from the point of evaluation.

• Heuristically, these time scales allow us to identify the dominant coarsening mechanism in different regimes.

• The dynamics of the coarsening process is driven by the reduction of total energy.

• In some places the upper parts of the coarsening-upward sequence are eroded by the distributary channels as a result of progradation.

• Numerical results are presented to confirm part of the analysis and to explore the difference between the two models on coarsening dynamics.

• By coarsening we mean in particular the decrease of the number of droplets in time.

• Our numerical results clearly distinguish different stages of coarsening such as the initial preparation and the alternating rapid structural transition and slow motion.

• The third type of cycle, up to 6 m thick, consists of thickening- and coarsening-upward calcareous sandstone beds and thin interbedded mudstones.

• Each cycle consists of thickening- and coarsening-upward non-channelized calcareous sandstone beds and blue-grey thin bedded mudstones.

• However, it is worth mentioning that the coarsening process is extremely slow.

• After some initial period, islands form in the substrate, where the number of islands decreases over time, whereas their size increases, a process called coarsening.

• They identify regimes in terms of the precursor height and the average film height where each of the coarsening mechanism is dominant.

• Coarsening-upward cycles record the repeated progradation and abrupt abandonment of fan lobes.
