Dear Lammps users,
I am using lammps to investigate a crack under mode 1 deformation (pls. see the attached picture for a better overview). As I understood, move command is working well with non-periodic BC. But, when I use move command with a high velocity, e.g. 0.1 Å/psec, the fixed layers from the two sides, on which move command is applied, will be disconnected from the rest of the material. And when I use a smaller velocity, e.g. 0.001 Å/psec, the deformation becomes extremely slow and even after like 100000 steps I don’t see a considerable deformation. Does anyone has an experience using move command in this regard?
I appreciate any suggestion and comment.
