Hi Li Ki,<div>Asterisks appear in the output when the value is too large to fit into the specified format width. Most of the time, this indicates some underlying problems in the calculation. For polarizability, the ground state should be well converged. You can confirm this if all other values before the asterisks are physical. <span style="font-size: 14px;">If then you still think it is a formatting issue, you can increase the format width in the relevant lines in motion/vibrational_analysis.F to increase the format width.</span></div><div><span style="font-size: 14px;">Best,</span></div><div><span style="font-size: 14px;">Beliz</span></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Friday, 4 July 2025 at 12:11:13 UTC+2 li ki wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Dear all, I hope this message finds you well. While performing polarizability tensor calculations using <b>cp2k</b>, I encountered an issue where many asterisks (******************) appear in the output, causing some data to remain undisplayed. I am unsure whether this might be related to some settings during the calculation process or due to the symmetry of the system, leading to certain components being either uncomputed or unnecessary to display. If anyone has insights into this issue or suggestions for resolving it, I would be very grateful for your guidance! <div><img alt="{D5357EBE-6DB3-4c5b-B2E6-DFE76DF28DBD}.png" width="534px" height="150px" src="https://groups.google.com/group/cp2k/attach/4ff672961cf01/%7BD5357EBE-6DB3-4c5b-B2E6-DFE76DF28DBD%7D.png?part=0.1&view=1"><br></div></blockquote></div>
