WebE: Must define dihedral_style before Dihedral Coeffs: Must use a dihedral_style command before reading a data file that: defines Dihedral Coeffs. W: Dihedral style in data file differs from currently defined dihedral style: Self-explanatory. E: Invalid data file section: Improper Coeffs: Atom style does not allow impropers. E: Must define ... WebMar 3, 2024 · Description. The hybrid style enables the use of multiple dihedral styles in one simulation. An dihedral style is assigned to each dihedral type. For example, dihedrals in a polymer flow (of dihedral type 1) could be computed with a harmonic potential and dihedrals in the wall boundary (of dihedral type 2) could be computed with a helix …
WebIf dihedral coefficients are specified in the data file read via the read_data command, then the same rule applies. E.g.
