One potential thing that could be causing issues is if you are importing temperatures from external sources, you need to have an individual applied temperature object in the tree for each stage, even if the source is from the same data file.&nbsp; For example here is a generic gas turbine model which has a 2D thermal analysis result for the entire assembly:&lt;\/p&gt;&lt;p class=&#8221;x_MsoNormal&#8221;&gt;<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/04\/24-04-2024-1713966672-blobid0.png\" width=\"1516\" height=\"769\" \/>&lt;\/p&gt;&lt;p class=&#8221;x_MsoNormal&#8221;&gt;&nbsp;&lt;\/p&gt;&lt;p class=&#8221;x_MsoNormal&#8221;&gt;You can see that there are 7 unique imported body temperature objects even though they all come from the same source result file.&nbsp; Each of the imported body temperature objects are scoped to just the bodies for that stage.&nbsp; This model has 7 stages and each has its own temperature object in the tree.&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-363972","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"For the NLGEOM question - within a static analysis, typically the setup will include HI=0 sectors.
