Category:Electrostatics
Computing the properties of charged and dipolar systems requires proper treatment of the electrostatics. Without appropriate corrections, the energies, forces, and potentials will not correspond to the expected boundary conditions. This page provides a summary of the corrections that are implemented and the relevant INCAR tags to activate these corrections. Practical details regarding convergence, setting up, and running relevant calculations can be found in the how-to section.
Summary of relevant INCAR tags
The table contains a summary of INCAR tags for performing monopole, dipole, and quadrupole corrections. Please see the relevant pages of the respective tags for more detailed information.
