BN如何建模
|
|
如何用lammps建立六方結構的氮化硼(h-BN)的模型?順便幫忙看一下我這樣建模的問題。附件是h-BN的晶體結構。 # ------------------------ INITIALIZATION ---------------------------- units metal#單位? dimension 3 boundary p p p atom_style atomic #neighbor 2.0 bin #neigh_modify one 5 lattice hcp 2.5 # ----------------------- ATOM DEFINITION ---------------------------- lattice custom 2.5 a1 0.23 0.0 0.0 a2 0.0 0.39 0.0 a3 0.0 0.0 0.38 & basis 0.5 0.0 0.0 basis 0.0 0.5 0.0 basis 0.5 0.0 0.5 & basis 0.0 0.5 0.5 region whole block 0 5 0 5 0 5 create_box 2 whole create_atoms 2 box basis 1 1 basis 2 2 basis 3 1 basis 4 2 # ------------------------ FORCE FIELDS ------------------------------ # Tersoff Potentials pair_style tersoff pair_coeff * * BNC.tersoff B N mass 1 10 mass 2 14 ###################################### write_data data.BN # EQUILIBRATION reset_timestep 0 timestep 0.001 velocity all create 300 12345 mom yes rot no fix 1 all npt temp 300 300 1 iso 0 0 1 drag 1 # Use cfg for Ovito #dump 1 all custom 10 dump.comp.* id type xs ys zs c_csym c_eng c_strs[1]& c_strs[2] c_strs[3] #dump_modify 1 element B N # Set thermo output thermo 1000 thermo_style custom step lx ly lz press pxx pyy pzz pe temp # Run for at least 10 picosecond (assuming 1 fs timestep) run 20000 unfix 1 # Store final cell length for strain calculations variable tmp equal "lx" variable L0 equal ${tmp} print "Initial Length, L0: ${L0}" ###################################### # SIMULATION DONE print "All done" 75X]CK@5]Y8QCUUYZ)W@KBO.png |
