[SIESTA-L] vdw interaction and pseudopotentials

2016-10-15 Por tôpico Zara Nosh
Dear all, I would like to study the interaction between 2 organic molecules (contains O, H, and C atoms). As the first step I relax ​ed​ the structure ​ ​(​ using ​ dft-input= 'vdw-df' ) . Using vdw-df we should use rev-pbe pseudopotential but it seems that my results from blyp+vdw-df is better

Dear all, I would like to study the interaction between 2 organic molecules (contains O, H, and C atoms). I calculate vdw forces with vdw-df algorithm which should be used rev-pbe pseudopotential but it seems that my results by blyp+vdw-df is better that revpbe+vdw-df. Can we use blyp pseudopotent
