11.7.7 FDE-Man output

(September 23, 2025)

In general the FDE-Man output indicates all important stages of the embedding calculation, which are:

1.

Generation of $\rho_{A}^{\mathrm{ref}}(\mathbf{r})$ ,
2.

Generation of $\rho_{B}(\mathbf{r})$ ,
3.

Construction of the embedding potential,
4.

Start of FDE-Man embedding calculation and
5.

Final FDE-Man summary.

In the following table definitions of the terms printed to the output are collected. These quantities are printed for every state, i.e. for every $\rho_{A}^{I}(\mathbf{r})$ . In addition, the non-electrostatic interactions with respect to the reference density $\rho_{A}^{\mathrm{ref}}(\mathbf{r})$ are printed at the top of the FDE-Man summary.
