Dear SIESTA users Currently I'm using VIBRA package in SIESTA to calculate the phonon dispersion relation of monolayer h-BN. When I choose the supercell size more than 3*3*0, "Segmentation fault" is always reported, even when a small Meshcutoff (smaller than 50Ry) was chosen. The workstation I used has two 6-core CPUs and 24GB memory. Is the hardware the limiting factor or does the problem come from elsewhere?
Thanks.
