Dear Wien2k users,<div><br></div><div> I have a question regarding volume optimization and force minimization. </div><div><br></div><div>If I do volume optimization and force minimization for non magnetic calculation and then use that optimized volume and structural coordinates as input for the calculation of volume optimization and force minimization including spin polarization, spin orbit coupling term and LDA+U term, then whether I get the correct optimized values for both volume and coordinates of the structure which really need those corrections? </div>
<div><br></div><div>If I want to do volume and coordinates optimization including those correction terms from the begining then it will take a very long time. But if we do the optimization using non magnetic calculation to reach closer to the actual energy and force minima and then put those optimized structure for non magnetic calculation for the optimization of the structure having those corrections it may take lesser time to reach the actual minima. But whether we really get actual minima in this way?</div>
<div><br></div><div>The above two questions actually are the same questions. I am very sorry for that reapeating. Actually I want to make clear my intentions to the wien2k users.</div><div><br></div><div>Thanks in advance.</div>
