&lt;p&gt;&lt;span style="background-color:#008000;color:#ffffff;font-size:150%;"&gt;&lt;strong&gt;Answer:&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;One can limit the deflection of the column in the Wind screen by entering a value in &amp;ldquo;Maximum&amp;nbsp;deflection&amp;rdquo;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;If no value is input, the maximum deflection will be&amp;nbsp;limited at H/200 for French and German wind code and&amp;nbsp;H/240 for other codes (H is the total height of the&amp;nbsp;column).&lt;/span&gt;&lt;br /&gt;&lt;span style="color:#008000;"&gt;The value of the liquid height on tray may also limit the&amp;nbsp;deflection of the column.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;It&amp;rsquo;s a recommended good practice to not have an&amp;nbsp;overflow due to the deflection (refer to the sketch&amp;nbsp;below).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/36425.1.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-41/36425.1.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/23323.2.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/640x0/__key/communityserver-wikis-components-files/00-00-00-00-41/23323.2.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;Height of Liquid on Trays:&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;If the vessel has trays, AutoPIPE Vessel considers that operating liquid on the trays should not overflow due to&amp;nbsp;the wind loading.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;The height of liquid on the trays must be input (Typical value = 5mm).&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;The smaller the water height the greater the thickness (stiffness) of lower part of the vessel to resist therotation.&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:60px;"&gt;&lt;span style="color:#008000;"&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-00-41/8524.3.png"&gt;&lt;span style="color:#008000;"&gt;&lt;img alt=" " src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-00-41/8524.3.png" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p style="margin-left:30px;"&gt;&lt;span style="color:#008000;"&gt;The software calculates the angle a = atan (h/D) and that gives the maximum rotation at this level&amp;nbsp;h is the height of liquid and D the internal diameter of the vessel&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
