<p>Good day!<\/p><p> <\/p><p>I am trying to learn the basics on how to simulate a piezoelectric energy harvester where the end result is a graph of voltage created within the piezoelectric body as a reaction to an applied force. I have tried many methods of approach such as Modal with Harmonic Response, Modal with Coupled Field Harmonic and Modal with Static Structural, but none of these have been successful as I have always ran into some error I couldn’t work out. Now, after reading through the Help Manual and what it has to offer regarding piezoelectric bodies, I tried Modal with Coupled Field Modal, and for the first time I got to complete the simulations without problems. However, the Help Manual wasn’t clear on what exactly the voltage results represent, so I have come here to ask for clarification, because I have a feeling it is still not exactly what I’m looking for; What is the electric voltage result based on, where exactly does it come from in this simulation as in what creates it? It isn’t based on an applied force, that’s for sure, since that cannot be inputted into Coupled Field Modal, but I would like to know if it’s close to that. Thanks a bunch for helping me!<\/p><p> <\/p><p>Here are a couple screenshots of my setup and settings, as well as one specific voltage simulation result on the piezoelectric body of the assembly to visualize my problem. <\/p><p><\/p><p><\/p><p><\/p><\/p>\n","protected":false},"template":"","class_list":["post-396855","topic","type-topic","status-closed","hentry","topic-tag-mechanical"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["396855"],"_bbp_author_ip":["85.129.8.210"],"_bbp_last_reply_id":["397038"],"_bbp_last_active_id":["397038"],"_bbp_last_active_time":["2024-12-11 08:37:44"],"_bbp_reply_count":["3"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["483673","58821"],"_btv_view_count":["144"],"_bbp_topic_status":["answered"],"_bbp_subscription":["58821","483673"],"_bbp_status":["publish","answered"]},"test":"loant22student-sdu-dk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396855","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396855\/revisions"}],"predecessor-version":[{"id":397039,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396855\/revisions\/397039"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=396855"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
