各位老师好,我做了显式水和碳纳米管的气固体系研究PPCPs的吸附,在结构优化中没有加隐式溶剂化模型,现审稿人要求添加AIMD或是显式水分子与隐式溶剂化模型结合。 因为分子数太多也不稳定,AIMD尝试都失败了。然后直接用之前结构优化的结构上算了加SCCS的能量(RUN_TYPE ENERGY),但是吸附能结果都是正的。之前单加了显示水的吸附能是负的,单加溶剂化模型的也是负的。现在结合之后是不是属于过度计算,重复了;或者我理解错了审稿人的意思。还是这个结果是正常的,水分子本来就会竞争吸附位点。 麻烦各位老师指点,谢谢各位老师。 审稿人意见如下:The use of a static "explicit water" model is prone totrapping in local minima. The authors should validate the stability of waterconfigurations using short ab initio Molecular Dynamics (AIMD) simulations or,at minimum, couple the explicit water molecules with an implicit solvationmodel (e.g., SMD) to accurately reflect the bulk dielectric environment. &SCCS ALPHA [mN/m] 57.2 BETA [GPa] -0.5 GAMMA [mN/m] 0.0 DIELECTRIC_CONSTANT 78.36 EPS_SCF 0.2 #SCCS is activated only if SCF iteration is converged to this threshold EPS_SCCS 1E-6 #Requested accuracy for convergence of polarization charge density iteration MAX_ITER 150 #Maximum number of polarization charge density iterations DERIVATIVE_METHOD CD5 #Method for calculation of numerical derivatives.
