<div>Dear all,</div><div>I performed a Cell-Optimization of an experimental Metal-Organic Framework. Using PBE and GrimmeD3 dispersion functional, I got an optimized cif, where the XRD pattern agrees well with experiments and the structure looks fine. I wanted to do a systematic studies to test different functionals. When I optimised the structure using the SCAN and RVV10 functional, the resulting system seems to be under a lot of strain and the diffraction pattern doesn't agree with the experiments anymore. I attach my input, output and cif for the scan run and the optimised structure with the PBE functional.</div><div><br></div><div>Does anyone have an idea what went wrong here/what tests I can perform?<br>I was thinking it might be a problem with my SCF, so doing a convergence test or maybe a test in the basis or grid.</div><div>Thank you!<br></div>
<p></p>
