<div>Dear CP2K Users,</div><div><br />I attempted a CELL_OPT calculation using the revPBE0 functional, but unfortunately, the calculation is not converging, and after a few steps, the structure deviates significantly from the experimental one.<br />I chose to use revPBE0 with CP2K because, in CASTEP, I found a good agreement between the experimental and calculated structures using the revPBE functional. However, my computational resources are insufficient to test revPBE0 in CASTEP.<br />With CP2K, this is possible due to the Auxiliary Density Matrix Methods that reduce computational costs. Unfortunately, the calculation with CP2K does not converge.</div><div>I would appreciate any suggestions regarding this issue.<br />I have attached the CP2K input and outputĀ files, along with the CASTEP input and output.</div><div><br />Thanks in advance for your help!<br /></div>
<p></p>
