When we want to solve an eigenvalue problem to obtain load buckling factors the structure have to be manually divided into small elements.&nbsp;Otherwise we&nbsp;could&nbsp;get a huge error, although the program tells the user that an error is very small as we can see&nbsp;in Fig. 1 and 2.</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Undivided beam elements.png" style="width: 705px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/431798iDACE193172A84FF0/image-size/large?v=v2&amp;px=999" role="button" title="Undivided beam elements.png" alt="Undivided beam elements.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Divided beam elements.png" style="width: 705px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/431799iC3ED6D6F9339BACD/image-size/large?v=v2&amp;px=999" role="button" title="Divided beam elements.png" alt="Divided beam elements.png" /></span></P> Tue, 28 Nov 2017 13:26:00 GMT https://forums.autodesk.com/t5/robot-structural-analysis-forum/error-in-buckling-analysis/m-p/7578391#M38540 rholubowski 2017-11-28T13:26:00Z https://forums.autodesk.com/t5/robot-structural-analysis-forum/error-in-buckling-analysis/m-p/7634512#M38541 <P>Hi&nbsp;<a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/5312308">@rholubowski</a></P> <P>&nbsp;</P> <P>This error almost in all other softwares also&nbsp; and many codes require when you do p-delta analysis to divide the members.</P> Tue, 19 Dec 2017 09:53:41 GMT https://forums.autodesk.com/t5/robot-structural-analysis-forum/error-in-buckling-analysis/m-p/7634512#M38541 mustafahesenow 2017-12-19T09:53:41Z
