WebSep 13, 2011 · There are a few possible fixes: A structurally-consistent U procedure involves calculating U at the DFT level, relaxing the structure with that DFT+U value, recomputing U on the DFT+U structure, and so on until a consistent result is achieved [2]. This approach can reduce problems with bond over-elongation significantly.
