我文章中需要有一段内容对一个算法进行描述,但是不知道该如何描述啊,不知道自己描述的全不全面正不正确呢,完全不懂计算的东西啊,希望懂的人帮我看看有没有什么错误,非常感谢...
具体计算参数见附件,
我的描述是:
Theoretical calculations were performed by using dispersion-corrected density functional theory (DFT-D) provided by the DMol3 code. [1,2] We used the standard parameter set of Grimme without any parameter optimization. The atomic orbitals were represented by a double-numeric quality basis set with d-polarization functions (DNP). All the calculations were all-electron ones and performed with the Extra-Fine mesh. A self-consistent field procedure was done with a convergence criterion of 10-5 a.u. on the energy and electron density. The geometries and hydrogen bonds obtained with DFT-D were in good agreement with experimental values.

非常非常感谢
