quantum chemistry - Why does the SCF not converge in a …
WebNov 4, 2014 · Hi Dr. Defusco, I just tried to use gamess to do the SPE calculation with wavefunctions from turbomole included, but it is not converged. The basis set used is … WebJan 11, 2016 · The scf run converged in 27 iterations but the relax run does not converge and keeps on oscillating in scf accuracy. Why is this happening ? Is it because of the pseudopotentials ? I am new to quantum espresso. Please give some suggestions. I have attached my input file below. Thank you.. !   &control    calculation='scf' chronicles youth band
ORCA convergence problems? ResearchGate
WebHowever, while running the molcas tests using export MOLCAS_NPROCS=4; pymolcas verify .basic most standard tests failed after some tens or hundreds of scf/rasscf cycles. It seems that most runs face with convergence (or maybe any numerical) problems. WebMay 8, 2024 · Dear All, I've been trying to perform a CELL_OPT for Cu2O but the calculation sadly cannot converge the SCF cycles. I tried all possible OT preconditioners with CG as minimizer by cp2k 6.1 edition which all failed and spin contamination even occurred under full_all condition. I also tried the increase of max_scf from 100 to 400 as well as the ... http://bbs.keinsci.com/thread-28703-1-1.html chronicles wqln
