Witryna30 kwi 2024 · 之前我们说到，如何将LAMMPS正常运行，并对LAMMPS的in文件和输入文件进行修改调试，查看结果。可以说，基本与科学无关，纯属dirty work。但科学也是在dirty work的基础上架构的。 这一次，我们准备触及分子动力学的中的物理内核。 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 …
