QC-SCF not implemented/tested for DFT

Post by wanghong » 12 Jun 2019, 02:58

Dear Dalton Community:
When I do SOC calculation, the output file always fails to output normally.And there are always five warnings.(1) for example: WARNING!!!DIIS aborted because Max DIIS iterations!"I have added the.max DIIS command in the input file, but the error still appears.(2) "QC-SCF was not tested for DFT."I didn't find any instructions in the DALTON manual.
Looking forward to your reply!

The DIIS is not converging, so it does not help with more DIIS iterations. You could try to give it a bigger level shift, e.g.:

Code: Select all

*SCF INPUT
.SHIFT
 -1.0
