I tried using a porous medium in the mixture, but it had difficulty converging. Then I used the Eulerian method, and it worked. However, the fluid did not penetrate the walls. The porosity value was correct. What I&rsquo;m confused about is the direction; the inlet is located exactly in the center. Should the direction value be set to 1 for the remaining cells, or should it be set to direction 2?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-460932","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["460932"],"_bbp_author_ip":["103.212.43.198"],"_bbp_last_reply_id":["460956"],"_bbp_last_active_id":["460956"],"_bbp_last_active_time":["2026-07-07 08:41:34"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["600754","199"],"_btv_view_count":["72"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["199"]},"test":"2210912041_alamirsyahstudent-unand-ac-id"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/460932","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\/460932\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=460932"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
