I have a problem and I am wondering if anyone can help me.<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>I have a simulation set up where I have a rotating arm inside a hexagonal enclosure. The simulation is set up with a turbulent model with air as the fluid. I created a Boolean around the arm (Boolean 1) and then another Boolean (Boolean 2) around the first Boolean. Boolean 1 is the cylinder and Boolean 2 is the hexagonal enclosure. Boolean 2 is set as the enclosure and has no inlets or outlets. My aim for the simulation is to show (with streamlines or vectors) the airflow around the arm as it rotates.<\/p>\n<p><\/p>\n<p>My issue is that in order to generate streamlines I need to specify a start point. If I do this then the streamlines will flow from that point forwards or backwards which will bounce off the enclosure walls and look messy. What I want is to show the arm moving and the streamlines moving round the arm as it moves. I am curious if this is possible and how I would go about setting it up?<\/p>\n<p><\/p>\n<p>The max speed of the arm will be around 150m\/s. I know the pictures show the speed is higher but this is just a test.<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Cheers,<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Iain<\/p>\n<p><\/p>\n<p>&nbsp;<img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/dab42980-ba7b-4f00-9518-a8ce00a2926b\/e099ddc2-8575-48d3-9386-a9a600b4d070_cfd-geometry.jpg?width=690&amp;upscale=false\" alt=\"\"><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/dab42980-ba7b-4f00-9518-a8ce00a2926b\/d2665b40-2ece-434d-a883-a9a600b4dd7e_cfd-post.jpg?width=690&amp;upscale=false\" alt=\"\"><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/dab42980-ba7b-4f00-9518-a8ce00a2926b\/b0f3685e-5b3a-41b2-a143-a9a600b4ec49_streamlines.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-31796","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["3968"],"_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","0","0","0","0"],"_btv_view_count":["2947"],"_bbp_subscription":["236170"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["31796"],"_bbp_forum_id":["27792"],"_bbp_engagement":["62","22555","156877"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["70893"],"_bbp_last_active_id":["70893"],"_bbp_last_active_time":["2018-11-29 09:27:21"]},"test":"iainb"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31796","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\/31796\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=31796"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
