Why did a set of identical AIMD runs in Quantum Espresso give different results?<https://mattermodeling.stackexchange.com/questions/14466/why-did-a-set-of-identical-aimd-runs-in-quantum-espresso-give-different-results>
I ran two spin-polarized AIMD calculations using QE, with identical parameters and input files. However, I observed that while in the first run, the SCF step converged without any issues, while in the second one, the SCF accuracy kept on increasing after a few steps. What could be the possible reason for this discrepancy?
