Sorry, I should never have brought it up.  A long time ago I was involved with simulating grain growth in solids (like steel).  If a person polishes the surface up properly, you can usually find where the grain boundaries are, and map them out.  How grain boundaries migrate when exposed to elevated temperatures, is to move towards the local center of curvature at a speed dependent on the local curvature.  Doing this might work better if the boundary is parameterised in terms of arc length.

Not really applicable to CAD.  Sorry.

Just in case you wanted to know.
