I made a workpiece via Atomsk and get the sharp tool in Ovito (tool with edge radius: I used comsol with stl file and put atoms using Atomsk. Before combining the tool and workpiece, diamond cubic structures of silicon and diamond tool were maintained along z-direction when view in Ovito. On combing them in Ovito, the atoms at the surface of the tool appear as neighbour diamond cubic(may I say nonperiodic). But when I used slice modifier pipeline in Ovito, the inner atoms in the tool remained cubic diamond structure. My questions is will the neighbour atoms have effect on my simulation results and analysis. Is there any other means to get the models? I tried region commands in Lammps but I couldn’t get the commands right esp. tool with edge radius and angles
