Hi Matt,
Thx for the update. I have tested all of EXCH_CORRECTION_FUNC keywords, and
only BECKE88X and PBEX work well. The rest keywords (i.e. DEFAULT, NONE and
OPTX) are all crashed due to the same error massage.
Meanwhile, in my case where B3LYP was applied in TDDFPT, the PBEX gave me a
very bad excitation energy.
TDDFPT WAVEFUNCTION OPTIMIZATION
Step Time Convergence Conv. states
--------------------------------------------------
State Exc. energy (eV) Convergence (eV)
1 -3517.6249333 -3.5214E+03
2 -41.0249219 -4.5343E+01
3 -28.5182648 -3.2893E+01
1 131.6 1.2941E+02 0
State Exc. energy (eV) Convergence (eV)
1 ************** -1.8816E+06
2 ************** -1.7503E+06
3 ************** -1.3091E+06
.......
Therefore we don't have too many choices, and must be very careful when
chosen EXCH_CORRECTION_FUNC keywords.
Hopefully this can be fixed soon~
Thank you again, Matt!
