BPARAM

BPARAM = [real]
Default: BPARAM = 6.3

Description: The tag BPARAM specifies the value of the parameter $b$ in the kernel of the nonlocal rVV10 correlation functional.

BPARAM should be set to 6.3, 15.7, 10, or 11.95 for the rVV10,^[1] SCAN+rVV10,^[2] PBE+rVV10L,^[3] and r $^{2}$ SCAN+rVV10 ^[4] functionals, respectively.
