A question about wannier tutorial tw90_4

Post by localspin » Wed Mar 09, 2011 4:03 am

Hello everybody. recently i was learning the turorial aboout abinit+wannier90. Today i've read the wannier90 input tw90_4o_DS3_w90.win of the tutorial tw90_4. And i found these words:

Code: Select all

!everything below can be copied from the wannier90.nnkp file output
! after the initial abinit wannier run


the following of these words are "begin unit_cell_cart"and "begin kpoints" blocks.

my question is that, at the first run of abinit + wannier, these blocks are needed. But there are saying, these blocks can be copied from the wannier90.nnkp file output after the initial abinit wannier run. it seems to be a paradox.

how do you think about it?

looking forward your reply!

These blocks are not necessary for the abinit + wannier run, just if you restart a stand-alone wannier run afterwards. These blocks are read from the abinit input file.
