Controls density fitting for the Coulomb problem. Density fitting basis sets are specified as part of the model chemistry within the job's route section, discussed here. DenFit is a synonym for this keyword.
Iterative
Controls whether a generalized inverse is formed or the fitting equations are solved iteratively. NonIterative is the default except for ADMP.
InvToler=N
Set the tolerance for a non-trivial eigenvalue of the generalized inverse of the fitting matrix to 10-N.
Convergence=N
Specifies 10-N as the convergence criterion for iterative solution of the fitting equations. Implies Iterative. The default is 10-6 for ADMP and 10–9 for the BOMD.
Applies only to DFT calculations using pure (non-hybrid) functionals.
