&lt;p&gt;Creating a dummy shell will all you to analyze a single shell to up to 3 different design conditions. To create one you start by creating a horizontal vessel with saddles from the templates.&lt;/p&gt;
&lt;p style="padding-left:150px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Horizontal-Vessel-Template.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;The specified vessel code does not matter so much but we will need to input a design pressure and design temperature:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Pressure: 1 MPa&lt;/li&gt;
&lt;li&gt;Temperature: 100&amp;deg;C&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Be sure to click through all the tabs of the Vessel Properties dialog and not to forget to assign materials for the vessel.&lt;/p&gt;
&lt;p&gt;You should get a vessel similar to the one shown below:&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Horizontal-Vessel.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;You can delete the saddles for the purpose of this demonstration.&lt;/p&gt;
&lt;p&gt;Click on the shell and then right click to select the &amp;ldquo;Split Shell&amp;rdquo; command and split the shell into the following lengths:&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Split-Shell-Input.jpg" /&gt;&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Split-Shell.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;Select the middle shell and change the length to zero and remove the checkbox for &amp;ldquo;Pressure Bearing&amp;rdquo; which creates the &amp;ldquo;dummy shell&amp;rdquo;.&lt;/p&gt;
&lt;p style="padding-left:90px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Dummy-Shell-Input.jpg" /&gt;&lt;/p&gt;
&lt;p style="padding-left:60px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Dummy-Shell.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;You can now go back to the vessel properties dialog to insert your extra shell design properties for the &amp;ldquo;second&amp;rdquo; chamber:&lt;/p&gt;
&lt;p style="padding-left:90px;"&gt;&lt;img alt=" " src="/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-41/Dummy-Design-Input.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;Something to keep in mind with this dummy shell is it creates a line of support for consideration in designing for external pressures. If you are designing for external pressures and need this dummy shell, you will need to insert a stiffener on the split of the shell to accurately take into account this line of support.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
