Fig.1 shows grain coalescence due to limited number of order
parameters. Using a coarse grain structure as input,
with as many order parameters as grain orientations
eliminates grain coalescence, as shown is in Fig. 2.
Monte Carlo simulation with the same initial grain
structure as in Fig. 2 also shows no coalescence (Fig. 3)
