Extract grains by their neighboring phase

[Sören T]

Good day

this question is rather simple but somehow I can't get mtex to do what it is supposed to.

My aim: I want to get a variable which includes all grains from phase A (Forsterite) which share a boundary with a specific phase B (Enstatite).

Something like that.

AB_grains = grains(grains.boundary('A','B'));

I guess it's quite easy to answer but ....I would be very glad for suggestions.

Thanks in advance!

Hi Sören,
easy answer: grains(unique(grains.boundary('A','B').grainId(:)))

Thanks a lot! Works fine!

One comment: If specific grains are deleted in advance i.e. outer boundary grains it's not working.
