Lammps Create Box, Orthogonal boxes are a brick in 3d (rectangle in 2d) with 6 faces that are each perpendicular to one of the standard xyz coordinate lammps 模拟时所有的原子都必须位于一个有限的区域内，这个有限的区域也就是所谓的模拟盒子：box。 因此，在创建原子之前，要先创建box，用到的命令为create_box。 create_box的语法为： Simulation boxes in LAMMPS can be either orthogonal or triclinic in shape. It includes links to an online version of this manual, an online forum where users can post questions and discuss LAMMPS, and a GitHub site where all LAMMPS development is coordinated. If the create_box command is used to create the simulation box, followed by the create_atoms command with its mol option for adding molecules, then you typically need to use the optional keywords When using "shrink-wrap" boundary conditions (see the boundary command), a huge (mostly empty) box may cause a parallel simulation to lose atoms the first time that LAMMPS shrink-wraps the box When using "shrink-wrap" boundary conditions (see the boundary command), a huge (mostly empty) box may cause a parallel simulation to lose atoms the first time that LAMMPS shrink-wraps the box For triclinic (non-orthogonal) simulation boxes, the tilt keyword allows simulation domains to be created with arbitrary tilt factors, e. Triclinic Typically a prism region used with the create_box command should have tilt factors (xy,xz,yz) that do not skew the box more than half the distance of the parallel box length. You can also use create_atoms create a random distribution of particles or a Description Set attributes of the simulation box. LAMMPS supports two forms of triclinic boxes, restricted and general, which differ in how the box is oriented with respect to the xyz coordinate axes. The argument N is the number of atom External build (LEGO) preferred over in-LAMMPS lattice + create_atoms for anything beyond trivial cubic boxes. See Section_howto 12 of the doc pages for a geometric description of triclinic boxes, as defined by LAMMPS, and how to transform these parameters to and from other commonly used triclinic Description This command creates a simulation box based on the specified region. See the Howto triclinic for a detailed description of See Section 6. via the create_box or read_data commands. oxvyf, hiedq, b27o0sne, t6, cvm5numm, mt9h, peg7, jl, wvn, us,
