Tīmeklis2012. gada 25. nov. · when checking bonds, angles, and dihedrals, LAMMPS checks, whether the image flags are consistent with the bonding pattern. it flags an error, when on of the coordinates is the "wrong" image. that usually is an error in the input. in rare cases, it can also be an indication of bad dynamics. 3. Tīmeklis这不是lammps问题，是力场问题。 A dihedral angle potentials depends on four consecutive bonded atoms, whereas the improper torsion depends on three atoms centered around a fourth atom. ... The main difference between both torsion potentials is the definition of the torsional angle and the functional form of the potential function.
