| Description: {{TAG|ALGO}}= timeev calculates the frequency dependent dielectric matrix after the electronic ground state has been determined using the time evolution algorithm (only available in vasp.6)
| |

| | |
| VASP posses multiple other routines to calculate the frequency dependent dielectric function.
| |
| Specifically, one can use {{TAG|ALGO}} = TDHF ([[BSE calculations]] equivalent to solving the Casida equation), {{TAG|ALGO}} = GW ([[GW calculations]]). For standard DFT, the timeevolution algorithm is
| |
| usually fastest, whereas for hybrid functionals {{TAG|ALGO}} = TDHF is
| |
| usually faster.
