&lt;p&gt;The removal of tubes in bundle layout can happen due to several reasons:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Maintaining pass tolerance like we saw earlier this week the model that we worked on&lt;/li&gt;
&lt;li&gt;To maintain height between tubes with impingement baffle&lt;/li&gt;
&lt;li&gt;To maintain the TEMA inlet outlet condition requirement when &amp;lsquo;compute&amp;rsquo; field in Bundle dialog box is checked to verify shell entrance and exit areas as per the TEMA calculations&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Bundle-Flow-Section-Calcs.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;If I remove the compute check option shown in above image&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Bundle-Flow-Compute-Off.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;There is no vacant space in bundle layout:&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Full-Tubesheet.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;See report section for this calculation when compute is checked and flow verification need to be performed:&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Tubesheet-report.jpg" /&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
