LVTOT = [logical]
Default: LVTOT = .FALSE.

Description: Determines whether the total local potential $V_{\text{LOCPOT}}(\mathbf{r})$ (in eV) is written to the LOCPOT file.

${\displaystyle V_{\text{LOCPOT}}(\mathbf{r}) = V_{\text{ionic}}(\mathbf{r}) + \int \frac{n(\mathbf{r'})}{|\mathbf{r}-\mathbf{r'}|}d\mathbf{r'}+ V_{\text{xc}}(\mathbf{r}) }$

where $V_{\text{ionic}}(\mathbf{r})$ is the ionic potential, the second term is the Hartree potential, and $V_{\text{xc}}(\mathbf{r})$ is the (semi-)local exchange-correlation potential.

If LVTOT=.TRUE., the $V_{\text{LOCPOT}}(\mathbf{r})$ is written to the LOCPOT file and the POT file. The POT file additionally contains the augmentation part.

Warning: LVHAR=T changes the content of the LOCPOT file.

WRT_POTENTIAL also gives access to the total local potential and offers more options.
