Instead, it had a pressure for each node and its corresponding XYZ coordinates. Maybe this could be problem, that Ansys Mechanical is not recognizing nodes because the .csv file refers to elements? nAny help would be appreciated. nn<\/p>\n","protected":false},"template":"","class_list":["post-54561","topic","type-topic","status-closed","hentry","topic-tag-ansys-aqwa","topic-tag-ansys-mechanical","topic-tag-aqwa","topic-tag-external-data","topic-tag-hydrodynamic-response"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["26896"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["??l"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["4818"],"_bbp_subscription":["232918"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["54561"],"_bbp_forum_id":["27791"],"_bbp_engagement":["200","183765","186528"],"_bbp_voice_count":["3"],"_bbp_reply_count":["11"],"_bbp_last_reply_id":["232654"],"_bbp_last_active_id":["232654"],"_bbp_last_active_time":["2021-05-14 17:30:22"]},"test":"floatingstones"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/54561","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\/54561\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=54561"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
