Hello,

I am using the R2SCAN functional, and I wonder if also the D3BJ parameters were implemented. In the case, what do I have to introduce in the input in the vdw_potential section?

Thank you in advance for the information,
Stefano

Hi

you can set the D3(BJ) scaling parameters in the input:

FORCE_EVAL / DFT / XC / VDW_POTENTIAL / PAIR_POTENTIAL/D3BJ_SCALING => s6,a1,s8,a2

There are no defaults in the code for the SCAN functionals. You have to look in the
literature if somebody has determined optimal parameters.

regards

Juerg Hutter
