I am a PhD student and wants to perform axi-symmetric simulation of capillary rise in fluent. I have a domain which is axi-symmetric with a capillary tube placed on one side, the dimension and the boundary conditions are mentioned.<\/p>\n<p>The red phase is the water and the blue phase is air. The capillary tube has a radius of 0.001 m. All the condition are at room temperature. The simulation is done at typical operaing condtion where the presssure is at 101325Pa and the operating density of air is 1.225kg\/m3. On the capillary wall the contact angle is 60 degree. The water moves all the way to the top of the tube which a pressure outlet boundary. VOF method is used for modelling and implied body force is used to model body forces. Also the simulation is conducted with axiy-symmetry in x-direction and g is taken as -9.81m\/s2 and the x-axis is used for axi-symmetry as per requirement by Ansys.<\/p>\n<p>I was wondering if the community could provide their insight about as it is totally confusing. I would be waiting for your kind response.<\/div>\n<div class=\"ps-post__attachments ps-stream-attachments ps-js-activity-attachments js-stream-attachments\">\n<div class=\"ps-post__attachment cstream-attachment photo-attachment\">\n<div class=\"ps-post__gallery ps-media-photos ps-media-grid ps-post__gallery--single ps-media-grid--single ps-clearfix\" data-ps-grid=\"photos\">\n<div class=\"ps-media-grid-padding\">\n<div class=\"ps-media-grid-fitwidth\"><img decoding=\"async\" src=\"https:\/\/community.ansys.com\/wp-content\/peepso\/users\/49454\/photos\/thumbs\/8c9a6684d426f2b6da842c26fa554fe5_l.jpg\" data-ajax-id=\"49454\" data-ajax-dir=\"users\" data-ajax-file=\"8c9a6684d426f2b6da842c26fa554fe5\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"template":"","class_list":["post-284565","topic","type-topic","status-closed","hentry","topic-tag-fluent-cfd-ansys-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["159206","199"],"_bbp_author_ip":["23.217.200.46"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1590"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["284565"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","159206"],"_bbp_voice_count":["2"],"_bbp_reply_count":["8"],"_bbp_last_reply_id":["285344"],"_bbp_last_active_id":["285344"],"_bbp_last_active_time":["2023-05-23 16:15:40"]},"test":"zakmt293"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/284565","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\/284565\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=284565"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
