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. Then the geometry optimization can be improved using GFN2-xTB.It can occur sometimes that a geometry does not converge correctly or at all if the calculation is … WebIn this case the project name should be consistent and the SCF_GUESS should be set to ‘restart’. Care should be taken that the wavefunction is a suitable guess for the SCF …
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.
