How to run wB97X-D3BJ or wB97X-D4?

Questions
#1

Hi,

I am curious about how to turn off the vv10 calculations in wB97X-v, and replace the vv10 with D3BJ or D4, as described in this paper
https://onlinelibrary.wiley.com/doi/10.1002/jcc.26411

if this is possible, we have much more flexibility. We can even manually implement the wB97X-3c method by using wB97X-V method + turning-off VV10 + customized D4 parameters + the customized vDZP basis.

Thank you,

Hi, not sure but could you not use NL_VV_C, NL_VV_B, and NL_VV_SCALE REMs to turn off VV10 if the NL_CORRELATION or USE_RVV10 REMs do not work in your use case?

Another workaround is that SCF_FINAL_PRINT = TRUE will print energy components after the SCF convergence, and will give you the nonlocal correlation (= VV10) energy. That won’t give you the efficiency that you want (because VV10 is still computed), but could work as a hack to implement this and get the energies.
