2012-11-02 Thread florence liu
Dear all, i am trying to do some optimizations with PWSCF v.5.0 and I have the following problem. I want to let a optimization to continue, even if the scf has not fully converged. As I have under stood the QE documentation, one need to set the tag scf_must converge, as i have done in my input file

Dear all, i have been looking through the file Modules/funct.f90 and i have found something which confuses me a little. according to the file the vdw-df2 functional is "defined" as "sla+pw+rpb+vdw2". however the corresponding reference (Lee et al., Phys. Rev. B 82, 081101 (2010)) mentions that the
