SCF at small ecut and restart at larger ecut?

Post by mdsimulationgroup » Sun Mar 10, 2019 1:25 pm

Hello,

What is the best way to do a single point calculation at a small ecut and then use the density file to start another calculation at a larger ecut? I am using PAW potentials.

Thank you!
Stacey

Dear Stacey,
I'm not 100% sure but I think you ca use the irdden flag https://docs.abinit.org/variables/files/#irdden and iscf<0, probably iscf=-2 in your case.
Best wishes,
Eric
