WebThe create_box, read data, and read_restart commands specify whether the simulation box is orthogonal or non-orthogonal (triclinic) and explain the meaning of the xy,xz,yz tilt factors. If fix deform changes the xy,xz,yz tilt factors, then the simulation box must be triclinic, even if its initial tilt factors are 0.0.

WebDescription. Change the volume and/or shape and/or boundary conditions for the simulation box. Orthogonal simulation boxes have 3 adjustable size parameters (x,y,z). Triclinic (non-orthogonal) simulation boxes have 6 adjustable size/shape parameters (x,y,z,xy,xz,yz). … Web// triclinic box: double xy, xz, yz; // 3 tilt factors: double h[6], h_inv[6]; // shape matrix in Voigt ordering // Voigt = xx,yy,zz,yz,xz,xy: double h_rate[6], h_ratelo[3]; // rate of box size/shape change: int box_change; // 1 if any of next 3 flags are set, else 0: int box_change_size; // 1 if box size changes, 0 if not

WebAlso note that if your simulation will tilt the box, e.g. via the fix deform command, the simulation box must be setup to be triclinic, even if the tilt factors are initially 0.0. You can also change an orthogonal box to a triclinic box or vice versa by using the change box command with its ortho and triclinic options.
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: irn faqWebAlso note that if your simulation will tilt the box, e.g. via the fix deform command, the simulation box must be setup to be triclinic, even if the tilt factors are initially 0.0.
