Hello,<\/p>\n

I’m currently trying to simulate a small flow through a pipe with varying diameters. I attempted to reduce the residuals in my steady-state simulation, but it didn’t work as expected. Therefore, I switched to a transient simulation.<\/p>\n

However, I’m encountering an issue with the total pressure values. In the transient simulation, the maximum total pressure at the inlet is 0.172 Pa, while in the steady-state simulation, it is only 0.069 Pa.<\/p>\n

Here are the residuals:
Steady:
<\/a><\/p>\n

Transient:<\/p>\n

<\/a><\/p>\n

 <\/p>\n

Could you please advise on why these differences might be occurring and how to address them?<\/p>\n

Thank you.<\/p>\n","protected":false},"template":"","class_list":["post-373826","topic","type-topic","status-closed","hentry","topic-tag-fluent-ansys-1","topic-tag-convergence","topic-tag-convergence-problem-1","topic-tag-fluent","topic-tag-residuals"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["2a00:8a60:c010:1::1:1101"],"_bbp_subscription":["440549","199"],"_btv_view_count":["193"],"_bbp_topic_status":["answered"],"_edit_lock":["1722162514:440549"],"_bbp_topic_id":["373826"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","440549"],"_bbp_voice_count":["2"],"_bbp_last_reply_id":["374050"],"_bbp_last_active_id":["374050"],"_bbp_last_active_time":["2024-07-29 15:20:46"]},"test":"074cbff84cfea328cfb618eaf430306becf5f7da"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/373826","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":3,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/373826\/revisions"}],"predecessor-version":[{"id":373829,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/373826\/revisions\/373829"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=373826"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
