In particular, I am looking at the impact of hydrofoils on motion reduction. I have already imported a hull geometry in .igs format into WorkBench v19 and run the radiation and diffraction analysis. However, when I add the foils (shown below), I encounter problems with the meshing.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/9fc051dd-d93e-4a41-b06c-aba50093cb54\/10903da9-c2ff-448b-92d5-aba5009a94e7_bow.jpg?width=690&amp;upscale=false\" alt=\"Ship's bow\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>To use Aqwa, I need to have a model with surfaces rather than solid bodies. I created the surfaces for the foils. However, I cannot cut out the surfaces of the main hull to remove the portion enclosed by the foils as shown below. If I use the Repair tool of SpaceClaim, I can get the Mesher to create a mesh; however, it excludes the fins. I have tried to use the Combine and Split options to cut the surface where the fins are, following the manual, unsuccessfully. With the Split command, how can I select the hole edge of the fins to cut the hull surface? These are surfaces with a complex curvature.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/9fc051dd-d93e-4a41-b06c-aba50093cb54\/a2c8d87e-7259-404e-8a19-aba5009c81a5_plane.jpg?width=690&amp;upscale=false\" alt=\"Hull surface\"><\/p>\n<p><\/p>\n<p>Many thanks in advance for your help!<\/p>\n","protected":false},"template":"","class_list":["post-43097","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["15278"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["1676"],"_bbp_subscription":["250295"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["43097"],"_bbp_forum_id":["27789"],"_bbp_engagement":["62","176124"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["112182"],"_bbp_last_active_id":["112182"],"_bbp_last_active_time":["2020-04-23 06:46:27"]},"test":"eanderlini"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/43097","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\/43097\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=43097"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
