<div>How can I project dos to molecular orbital? </div></blockquote><div><br>There is a post-processing tool called projwfc.x which you can use to project dos to molecular orbital.<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<div>what is the importance of nbnd in calculations for dos? </div></blockquote><div>e<br>"nbnd" tells the code the no. of Kohn-Sham states it has to compute.....While computing the dos, one wants to plot the dos for both the occupied & unoccupied manifold, the no. of energy levels is read in by the dos.x from the output of your scf/nscf run. So while doing an scf/ nscf calculations you can control the total no. of states with the variable "nbnd".<br>
Depending on the type of occupation scheme you choose the value of nbnd is nelec/2 (fixed occupation) or nelec/2+some extra bands (when you use smearing). If you want to plot the dos, usually you should add some extra levels using nbnd & do the scf or nscf calculations to get the unoccupied manifold. <br>
