Fix npt/body
Webfix prop all property/atom mol variable cluster atom ( (id-1)/10)+1 set atom * mol v_cluster. The atom-style variable will create values for atoms with IDs 31,32,33,…40 that are 4.0,4.1,4.2,…,4.9. When the set commands assigns them to the molecule ID for each atom, they will be truncated to an integer value, so atoms 31-40 will all be ... WebDimensions corresponding to unspecified parameters can also be controlled by a fix npt or fix nph command. The size and shape of the simulation box at the beginning of the simulation run were either specified by the create_box or read_data or read_restart command used to setup the simulation initially if it is the first run, or they are the ...

WebHi-level explanations of NEB are given with the neb command and on the Howto replica doc page. The fix neb command must be used with the “neb” command and defines how inter-replica nudging forces are computed. A NEB calculation is divided in two stages. In the first stage n replicas are relaxed toward a MEP until convergence.
