LSCDM method and w90?
Posted: Tue Mar 01, 2022 8:28 am
Dear all,
I noticed that also VASP has an implementation of LSCDM method to compute WannierFunctions, however,
although the code mentioned it I cannot get it to work. I am using the most recent VASP version (6.2.1), linked against W90 3.1. Then I try create a simple example for SrTiO3 perovskite the input looks as follows (see below),
although specified the code complains that no projections are defined and than w90 crashes consequently.
So is there a way to get this working?
