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.

WebNov 21, 2024 · Krack Matthias (PSI) That’s your decision depending on the system and the properties you are interested in, e.g. you will need k points, if you want to plot the band structure. On the other hand, a 3x3x3 supercell is roughly equivalent to using 3x3x3 k points with the 1x1x1 cell.

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. WebDec 1, 2024 · 2- If the energy of the final scf differs significantly, then it was converged to other state. In this case, the cure is to start a separate scf with new cell parameters and atomic positions. Moreover, I feel that using a relatively large mixing_beta may cause oscillation between metastable states and lead to no scf convergence.

WebAdditionally, the empty file NOT_CONVERGED is written. If convergence problems in the SCC occur, it is recommended to start with GFN0-xTB which does not have to perform SCC iterations.
