Zero Unit Cell Volume in Dispersion Calculation

Hi All, I'm following the RF2 tutorial (https://docs.abinit.org/tutorial/rf2/) to calculate the dispersion in a tetragonal unit cell. I've used the following unit cell parameters in other calculations without issue: acell 5 6 7 scalecart 1 1 .9640 rprim 1 0 0 0 1 0 0 0 1 But in this run, I'm now get...

Relaxation, letting space group change [SOLVED]

Hi, I'm trying to relax a cell using optcell = 0, so the ions can move, but not the lattice vectors. I'm also using ionmov =2. I've read elsewhere that this doesn't allow the space group to change (it maintains whatever space group your input xred gave). I want the space group to be able to change d...
