Hi,<div><br></div><div>I am doing single-point calculations of Li2CO3 with PBE functional, DZVP basis sets, and GTH pseudopotentials. Please see attached input file. However, I am getting different values of stress tensors when I am choosing analytical or numerical methods. When I am doing NPT simulations with the analytical method for stress tensor calculations, looks like volume is also overestimated. Do you know what can be a reason for this? Any help would be appreciated. </div><div><br></div><div>Below are snapshots of the output files.</div><div><br></div><div>Thanks,</div><div>Dina</div><div><br></div><div><img alt="analytical.png" data-iml="11187485.300000072" width="534px" height="407px" src="cid:c5b2f70d-bc6c-4a3b-a88d-69fc0064b8d0"><br></div><div><br><img alt="numerical.png" data-iml="11203232.800000072" width="534px" height="449px" src="cid:cb18e359-26c4-4120-a347-9f57996e8a21"></div>
