Grimme D3 size limit?
Posted: Mon Jul 01, 2019 3:09 pm
Folks,
I have a rather large system (>1300 atoms). It's a VdW crystal, so I need dispersion correction. If I try to optimise with IVDW=12, the SCF converges, but then the calculation dies (with signal 9, strangely). Is there a size limit I can get around by increasing a constant somewhere? The version is vasp.5.4.4 (Gamma-point).
Thanks in advance,
Herbert
