WebNote that the processors command allows some control over how the box volume is split across processors. Specifically, for a \(P_x \times P_y \times P_z\) grid of processors, it allows choices of \(P_x\), \(P_y\), and \(P_z\) subject to the constraint that \(P_x P_y P_z = P\), the total number of processors.This is sufficient to achieve good load-balance for …

WebThis fix computes a global scalar which can be accessed by various output commands. The scalar is an energy which is the sum of the spring energy for each atom, where the per-atom energy is 0.5 * K * r^2. The scalar value calculated by this fix is “extensive”. No parameter of this fix can be used with the start/stop keywords of the run command. WebNote. As discussed on the region command doc page, regions in LAMMPS do not get wrapped across periodic boundaries. It is up to you to ensure that periodic or non-periodic boundaries are specified appropriately via the boundary command when using a region as a wall that bounds particle motion. This also means that if you embed a region in your … WebID, group-ID are documented in fix command. thermal/conductivity = style name of this fix command.
