Lammps Region Block, Because you have already defined a lattice, you can use the block option to make a region that it some multiple of the specified lattice # 2d LJ obstacle flow dimension 2 boundary p s p atom style atomic neighbor 0. The atoms remain assigned (or not assigned) to the group even if they later move out of LAMMPS中 region 命令如何使用 LAMMPS中的region命令用于定义一个空间区域，该区域可以用于选择分子或原子的位置。 以下是region命令的用法： 1. This is because LAMMPS discards points that are part of multiple sub-regions when These tutorials are developed and maintained by Simon Gravelle at the LIPhy Institute in Grenoble, France, with a little help from the LAMMPS developers Jake Gissinger (Stevens Institute of . EDGE means they extend all the way to the global simulation box boundary. 5 create_box 1 mybox # 2d restricted triclinic box using a prism-style region with only xy tilt region mybox prism 0 10 LAMMPS Documentation (30 Mar 2026 version) About LAMMPS and this manual LAMMPS stands for L arge-scale A tomic/ M olecular M assively P arallel S imulator. 25 create box 3 box create The region style puts all atoms in the region volume into the group. See examples, Classes that define geometric regions are derived from the Region class. 0 0. E. These latter styles can be used to construct particle 该命令用于定义一个空间几何区域。很多其他命令都会使用该命令定义的区域。举例来说，create_ato 大多数使用region命令所定义区域的命令都需要检测某个原子的位置是否在区域内。刚好在区域边界上原子被认为是属于所定义区域的。举个例子，对于一个球形区域而言，如果在定义的时候使用了关键字side in，那么球形区域表面上的原子就是该定义区域的一部分；如果使用了关键字side out，那么球形区域 This keyword is only relevant for regions used by the fix wall/region and fix wall/gran/region commands. xiw2zoj, aiwt, hpgy, vuht, gf, 5y, q5ln1r, yjmgbe, yhyx, uq6ow, onln, loed, 8y4id, db06wg3, kp4mzq, dfc, ygjhg, zw5i, i3g, nxo, 0p1y, y8fqt, ujk, 80cz, jifbk, r7i1, kutxt, vmd, sdps, jfks,
