WebThis compute calculates a per-atom vector or per-atom array depending on the number of input values. If a single input is specified, a per-atom vector is produced. If two or more inputs are specified, a per-atom array is produced where the number of columns = the number of inputs. The vector or array can be accessed by any command that uses per ... 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 …
Modifying & extending LAMMPS. (Conference) OSTI.GOV
WebIn both variants the compiler would verify the existence of the property and correspondence of the signature. Normally you don't need to work with fields of the object directly, all definable properties are public and can be safely overloaded. WebWarning. If you use this command with the mol or charge vectors than you most likely want to set ghost yes, since these properties are stored with ghost atoms if you use an atom_style that defines them, and many LAMMPS operations that use molecule IDs or charge, such as neighbor lists and pair styles, will expect ghost atoms to have these … eastern bank site personal page personal aspx
