[CP2K:10698] CP2K 4.1 vs 6.1 Dispersion

[hut... at chem.uzh.ch]

Hi

sorry, that is my bad English

I meant the numbers calculated are clearly different (noticeable)
but the physics will not change (insignificant)

regards

Thank you for the response! What do you mean by notable, but non-significant changes in energy?

this is the only relevant change: 
! bug fixed 3.10.2017 
! correct value from alp6=14 to 16 as used in original paper 
! CALL damping_d3(rabc, r0, 4._dp/3._dp, alp6, rcut, fdabc, dfdabc) 
CALL damping_d3(rabc, r0, 4._dp/3._dp, 16.0_dp, rcut, fdabc, dfdabc) 
 
This leads to notable changes in energy, but they shouldn't be 
significant.

Hi, 
 
Have there been any changes in CP2K between versions 4.1 and 6.1 that would significantly change the result of the calculation for Grimme's D3 correction?  
 
Thank you, 
James Dean
