- | A __LOCPOT__ file containing the Hartree potential is produced during standart VASP run. One just have to care about a dipole correction (if necessary). The __LOCPOT__ file has to be convert into an *.xsf file, eg. via [[http://theory.chm.tu-dresden.de/~jk/software.html]] | + | A __LOCPOT__ file containing the Hartree potential is produced during standart //VASP// run.

- | where lx, ly & lz are shifting the output cube file so the written grid would be at the beginning of the Cartesian system. PPM can now read geometry from a cube file created by FHI-AIMS and shift it according to the shift of the cube cell; however for good run of the PPM calculation at least lz has to be properly specified. l = length of lattice vector / 2 - 0.05; But proper shift is used only, when the lattice vector follows some Cartesian direction. | + | where lx, ly & lz are shifting the output cube file so the written grid would be at the beginning of the Cartesian system.
