Dear LAMMPS Users,
Hi,
I’m doing a fracture test with ( P P S ) boundary condition. The point is I’m observing different behavior with different size in xy plane, i.e. 10times lattice constant vs. 30times of it, which shouldn’t be seen to the best of my knowledge as it is bulk in x and y and also the critical distance between atoms near the boundary up to the simulation box in x and y is smaller that the 1/2 cut off distance of my potential. Any comment on how to fix it ?
Thanks,
Ali
