how to start from initial charge density in SCF calc.

Post by koalad » Mon Jun 11, 2018 7:21 am

Hello abinit users!

Is there a way to start a SCF calculation from a provided charge density?

If I use getden it reads the density only for nscf calculations.

Can anyone help me with this?

Any comments would be most appreciated.

Thank you very much.

If you have a DEN file created from a previous Abinit run, you can use irdden 1 to read it at the start of a new calculation. getden only works in multi-dataset mode.
