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. WebBut when I performed a separate scf but with optimized cell parameters and atomic positions, I get the optimized value for pressure say 0.01 kbar, which is perfect. I am using QE-7.1. Does it mean that in the last scf run of vc-relax the diagonalised ocuupation matrices are used instead of the values specified in the input? Thanks in advance.
