After defining the material and applying a certain load to the PZT disk, I can get a voltage value from the disk. But this voltage is in open circuit condition. For example, by running the modeling in transient analysis and applying a dynamic load, the voltage signal exactly follows the strain signal, and of course, the value of voltage is too high like 30V. I could verify the voltage amplitude by the following equation to make sure my modeling steps are correct:<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/679\/V18OCWHBBMHQ.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/679\/V18OCWHBBMHQ.png\" alt=\"image.png\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-164468","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["1057"],"_bbp_likes_count":["0"],"_bbp_subscription":["254926"],"_bbpmt_movedon":["2022-07-01 16:39:50"],"_bbpmt_movedfrom":["151970"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["164468"],"_bbp_forum_id":["27793"],"_bbp_engagement":["50680","180812"],"_bbp_voice_count":["2"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["199223"],"_bbp_last_active_id":["199223"],"_bbp_last_active_time":["2021-12-15 17:28:23"]},"test":"ali_safian"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164468","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":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/164468\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=164468"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
