Dear all: I have a question on the difference between "bands" and "nscf" calculations.
Reading the manuals and readings in this forum, I know that (1) they are all one-step non-self-consistent calculations with use and fix of the charge density obtained in the previous "scf" calculations (2) "nscf" calculation is used for calculation of dos and in this "nscf" mode, unlike "bands" mode, the Fermi level and occupation numbers are calculated. But, I can't still understand clearly the difference between these two modes. I think that all types of calculations performed in "bands" mode, for example bands calculation, can be performed in "nscf" mode, too. Is it right? In addition, I would like to know the case for which only "nscf" mode should be performed, except for the calculation of dos.
