WebAn orthogonal box should give the same energy and force as a triclinic box when all the tilt factors are equal to 0.0, since the triclinic box isn't really tilted. However, if I add this line below to an input script using this PR I get significantly different forces and energies than the orthogonal case: WebJul 14, 2015 · The box vectors look like the following, where xy,xz,and yz, are the tilt factors. xlo = -0.34; xhigh = 40.466 ylo = -1.6283; yhigh = 49.50861 zlo = 0.77; zhigh = 39.79 xy = -8.62; xz = 0.0; yz = 0.0 ...

WebThe create_box, read data, and read_restart commands also determine whether the simulation box is orthogonal or triclinic and their doc pages explain the meaning of the xy,xz,yz tilt factors. If the displace_box command changes the xy,xz,yz tilt factors, then the simulation box must be triclinic, even if its initial tilt factors are 0.0.

By default, if your box is orthogonal, the LAMMPS data file does not contain information about the tilt factors (since they are all equal to zero).
