Make all 3 unpinning mechanisms disableable #4

Open arn-all opened 4 years ago

arn-all commented 4 years ago

Dislocations have 3 unpinning mechanisms here : 2 kinks coming from the same side piling up, 2 kinks from opposite side annihilating at the position of the solute, or the thermally activated unpinning from eq.(4) Zhao, Marian, MSMSE, 2018. To investigate the effect of each mechanism, each of them should be independently enable/disable-able from within the config file. Status :

Annihilation seems to be caused by lines 127-136, where neighbour kinks jump on one another, and lines 145-147, where they get deleted along with the screw segment that joins them.

But removing these two blocks leads to unstable, narrow double kinks that oscillate on the solute. Might not be worth fixing
