To simplfy I assume Absolute Pressure = Static Pressure. Problem is, when I want to define the presure &#8211; Saturation Tempearature piecewise-linear table I get the following Error: &lt;br&gt;&lt;br&gt;Pressure : [&#8230;] is greater than maximum.&lt;br&gt;Range is 0 to 30000&lt;br&gt;&lt;br&gt;I already tried switching from Pa to atm, but then the problem only presits with a maximium pressure of 0.29&#8230; atm. I also tried it approximating the Antoine eqation with a polynomial but it seems I&acute;m to dumb to enter the polynomial right. A preliminary solution would be a UDF but if possible I&acute;d like to stick to a picewise linear definition.&lt;br&gt;Thanks in advance&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-458843","topic","type-topic","status-publish","hentry","topic-tag-multiphase_models-1","topic-tag-condensation-evaporation-1","topic-tag-fluent","topic-tag-lee-model-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["458843"],"_bbp_author_ip":["2a00:8a60:c010:1::1:115e"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["458843"],"_bbp_last_active_time":["2026-05-26 08:12:30"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["1"],"_bbp_engagement":["637750"],"_btv_view_count":["15"],"_bbp_topic_status":["unanswered"]},"test":"ben-ludwigrwth-aachen-de"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/458843","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\/458843\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=458843"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
