Witryna3 gru 2024 · In our previous work [Surblys et al., Phys. Rev. E 99, 051301(R) (2024)], we have demonstrated that atomic stress could be used to efficiently compute heat flux for molecules with angle, dihedral, or improper many-body interactions, provided a newly derived “centroid” form was used. This was later successfully implemented in the … WitrynaTorsion terms are very important in determining the structure of 'organic' type molecules.
