WebMay 18, 2024 · Always start sgcpmd from a well converged wfn obtained along a standard BOMD run with diagonalisation and smearing. Let the first steps run on many scf iterations if needed, i.e., set MAX_SCF large enough. But use a relative large eps_scf. The wfn is not going to be optimised as in the BOMD, energy convergence around 10^-5 is desirable. WebEPS_JACOBI. EPS_JACOBI {Real} Below this threshold value for the SCF convergence the pseudo-diagonalization method using Jacobi rotations is activated.

If the inner SCF loop does not converge in the desired number of steps (set in MAX_SCF) then the inner loop will exit in order to prevent wasting time heading in the wrong direction. The preconditioner is recalculated and then a new inner loop SCF begins, with the number of outer steps ...
