What is dE - revisited
Posted: Mon Sep 27, 2021 8:25 pm
In an earlier post, there was this answer to the question of the meaning of dE
"dE always refers to some energy difference, but as there are many selfconsistency loops and minimization algorithms, e.g., the ionic relaxation, electronic relaxation, line minimization, and the diagonalization of the Kohn–Sham Hamiltonian, it might not be obvious which energy difference it refers to. A more detailed summary of each relaxation step can be found in the OUTCAR file!"
I am unable to find any reference to dE in the OUTCAR. What should I be looking for?
My problem is that the calculation converges and meets the electronic and force convergence requirements, but dE is huge (like 20). Is this OK or symptomatic of a deeper problem?
Thank you
