We recommend using PREC=Normal or PREC=Accurate. The chemical shielding tensor is defined as: = ()Here denotes the atomic nuclear site, and denote cartesian indices, an applied DC external magnetic field and () the induced magnetic field at the nucleus. I am trying to do DFT+U calculation for the material BaLaMn2O6 . per default. In spinor space, the part of the For noncollinear magnetic calculations, set LNONCOLLINEAR = True in the INCAR file and use the vasp_ncl executable. Generally, = 600 ALGO = Normal PREC = Accurate EDIFF = 1. (a) PBE SCF calculation with zero weight k-points. , non-spherical contributions from the gradient corrections inside the PAW spheres will be included as well. , the grid that is used to represent the augmented pseudo charge densities of VASP provides several different methods for relaxation, provided by specifying the ISIF tag (see here for details). VASP does not perform an actual calculation, only some important parts of the program will be executed and the timing for each part is printed out at the end. is the simplest one. However, when the self-consistency cycle fails to converge for one of the algorithms exploiting density mixing, e. , the information needed to compute the free-energy gradient is written in the REPORT file after each molecular-dynamics step ( MDALGO =1 | 2), check the lines after the header: Therefore VASP uses LMIXTAU=. All I found was the following: LSPIRAL, QSPIRAL - first one I assume is the flag for turning spirals on and second one gives the For noncollinear magnetic calculations, set LNONCOLLINEAR = True in the INCAR file and use the vasp_ncl executable. For semiconductors or insulators, use the tetrahedron method ( ISMEAR =-5), if the cell is too large (or if you use only a single or two k points) use ISMEAR =0 in combination with a small SIGMA =0. Mind: one has to specify one number for each , , , , , , For noncollinear magnetic calculations, set LNONCOLLINEAR = True in the INCAR file and use the vasp_ncl executable. Note that we did not explicitly print the polarizability here because VASP directly uses it to construct the dielectric SYSTEM = NaCl ALGO = Exact ISMEAR = 0 SIGMA = 0. In spinor space, the part of the If LAECHG=. 6 the contributions if you already run your DFT+U calculation in vasp, then just adding the "METAGGA = SCAN, LASPH = .

E-6 LASPH = T ! electronic dielectric function with Kramers-Kronig For VASP. I have run the DFT However, this method will prevent VASP from using symmetry to reduce the number of calculated points. 6, these contributions are only included in the total energy, after self-consistency has been reached disregarding the aspherical contributions in the gradient corrections. When LORBIT is set, VASP performs a post-processing step of the Kohn-Sham (KS) orbitals to decompose the KS orbitals into local quantum numbers and obtain local properties, e. Description: include non-spherical contributions related to the gradient of the density in the For VASP. NOT. There is now an option in ASE to automatically choose the VASP-recommended default pseudopotentials. LH5 Description: LWAVE determines whether the wavefunctions are written to the WAVECAR file at the end of a run. IALGO=2: Orbitals and one-electron energies are kept fixed.
