To approximate the inviscid and irrotational nature of potential flow, I used the &lt;em data-start=&#8221;401&#8243; data-end=&#8221;422&#8243;&gt;inviscid flow model<\/em> in ANSYS Fluent. However, the results did not match theoretical expectations.&lt;\/p&gt;&lt;p class=&#8221;&#8221; data-start=&#8221;502&#8243; data-end=&#8221;836&#8243;&gt;My goal is to capture classic potential flow characteristics (i.e., incompressible, irrotational, inviscid flow governed by Laplace&rsquo;s equation). From my understanding, Fluent does not directly solve for the velocity potential, and I have not found a clear recommendation in the documentation or related posters on how to achieve this.&lt;\/p&gt;&lt;p class=&#8221;&#8221; data-start=&#8221;838&#8243; data-end=&#8221;858&#8243;&gt;Could anyone advise:&lt;\/p&gt;<\/p>\n<ol>&lt;li class=&#8221;&#8221; data-start=&#8221;859&#8243; data-end=&#8221;924&#8243;&gt;&lt;p class=&#8221;&#8221; data-start=&#8221;862&#8243; data-end=&#8221;924&#8243;&gt;Whether Fluent can be used to accurately model potential flow?&lt;\/p&gt;<\/li>\n<p>&lt;li class=&#8221;&#8221; data-start=&#8221;925&#8243; data-end=&#8221;1023&#8243;&gt;&lt;p class=&#8221;&#8221; data-start=&#8221;928&#8243; data-end=&#8221;1023&#8243;&gt;If not, is there a workaround or a better-suited ANSYS tool or method for this kind of problem?&lt;\/p&gt;<\/li>\n<\/ol>\n<p>&lt;p class=&#8221;&#8221; data-start=&#8221;1025&#8243; data-end=&#8221;1067&#8243;&gt;Any guidance would be greatly appreciated.&lt;\/p&gt;&lt;p class=&#8221;&#8221; data-start=&#8221;1025&#8243; data-end=&#8221;1067&#8243;&gt;a related poster:&nbsp;&lt;\/p&gt;&lt;p&gt;https:\/\/www.cfd-online.com\/Forums\/fluent\/96173-modeling-potential-flow.html&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-430272","topic","type-topic","status-publish","hentry","topic-tag-2d-axisymmetric","topic-tag-CFDSolver-1","topic-tag-potential-flow"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["430272"],"_bbp_author_ip":["128.252.130.158"],"_bbp_last_reply_id":["430284"],"_bbp_last_active_id":["430284"],"_bbp_last_active_time":["2025-04-29 06:07:05"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["27819","436994"],"_btv_view_count":["199"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["436994"]},"test":"ll00023mix-wvu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/430272","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\/430272\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=430272"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
