2017-11-01 Thread Saif Ullah
Dear QE users, Can we use vdW-DF-c09x with revPBE pps or we need to build vdW-DF-c09x pp? Previously, I was told that no one generate PPs with vdW-df and in the funct.f90, I haven't found even a closer functional. Thanks Regards Saif Department of physics, UFJF, Brazil

This problem seems to arise if the moments go to zero (low spin solution). Perhaps it is dividing by zero (or a small number) as the moments decrease. With a large moment (high spin solution) the stresses seem to converge fine with -D__SPIN_BALANCED. --- Ronald Cohen Extreme Materials
