WebIn some cases, the option "-orthogonal-cell" may fail to find a suitable orthogonal box, typically when some box vectors form a very acute angle, or have lengths that are incommensurate. In such cases, it may help to use the option "-unskew" to reduce the tilt of the box before using the option "-orthogonal-cell". http://redmine.scorec.rpi.edu/anonsvn/lammps-cuda/doc/displace_box.html

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.

"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: " - Change box tilt factors for orthogonal box
