What is the difference between “stabilization” and “analytical_curvature” options in line:

# Shall grain type 1 be stabilized or shall
# an analytical curvature description be applied?
# Options: stabilisation analytical_curvature

Why do you stabelise grains? How do you stabelise the grains with these options?

The description in MICRESS Users manual is not clear:
“it can either be ‘stabilisation’ or analytical_curvature’, the latter being mostly suitable for grains whose radii are smaller than (or of the order of) the grid-spacing, the former takes affects only with grains which are smaller than a grid-cell.”

Dear mtoloui,

did you already have a look on these threads:

Reference2

Actually, this option is referring in first place to small grains, which still do not have a cell with full fraction. "Stabilisation" means to assume a reduced curvature in this stage instead of the phase-field curvature, and "analytical curvature" uses a full equivalent curvature instead of the phase-field curvature.
