<p>The problem is this:</p>
<ol>
<li>There are 157 rigid body modes in the system. This means some parts can move freely without causing deformation.<br/> Try to use the ‘Eigen Modes’-component and activate the display of local coordinate axes: The first eigen-mode will be the rigid body motion.<br/> If this does not help, check whether you have a pinned support directly attached to a hinge. A hinge introduces an extra node which may cause the problem.<br/> When analyzing a flat shell structure one has to lock the rotation perpendicular to the plate in at least one node.</li>

<p>I saw that you recommended using “Connected Parts (Karamba3D)” or "Eigen Modes (Karamba3D), but it seems like I have only one branch on my list.<br/> <a href="https://storage.ning.com/topology/rest/1.0/file/get/10918014299?profile=original" target="_blank" rel="noopener">20.12.3dm</a><br/> <a href="https://storage.ning.com/topology/rest/1.0/file/get/10918014661?profile=original" target="_blank" rel="noopener">karamba.gh</a></p> Yes, it does work, but there…tag:www.grasshopper3d.com,2021-06-21:2985220:Comment:21953062021-06-21T20:48:58.205ZKaramba3Dhttps://www.grasshopper3d.com/profile/karamba
<p>Yes, it does work, but there might be cases where it does not converge (<a href="https://manual.karamba3d.com/3-in-depth-component-reference/3.5-algorithms/3.5.3-analyze-nonlinear-wip" target="_blank">https://manual.karamba3d.com/3-in-depth-component-reference/3.5-algorithms/3.5.3-analyze-nonlinear-wip</a>)</p>

<p>Hi all, I am trying to use the arc-length method from your WIP and was wondering if it can be applied to shells. Thanks a lot in advance!</p>

<p>Dear Ilda,</p>
<p>please put together a sample definition which replicates the problem but does not contain extra components. Otherwise it is hard to spot the problem since it could be linked to the third-party components.</p>

<p>Hi,</p>
<p>Thank you for your prompt reply.</p>
<p>I am re-sending the code and also attaching a photo indicating the third party plugins. I am not sure which of them I should delete ?</p>

<p>Hi, can you please simplify your script and remove all third party plugins. We cannot debug your script when these extra components are included.</p>

<p>Hi,</p>
<p>I am having problem with the definition of boundary in a shell element.</p>
<p>The idea is for the panel I use, to have at the edges of the panel frame with larger dimensions since from the structural point of view in general these parts are being reinforced. The problem is that i used to create a boundary but i think it doubled the surface (panel itself + boundary surface).</p>
<p>Is there a way both surfaces to be merged in one surface and then it can be further analysed…</p>

<p>Hi, it is difficult to debug your problem without any screenshots or a definition.</p>
<p>Please also note that the Grasshopper forums are not regularly checked and you should post on our Rhino discussion board instead.</p>
<p>best,</p>

<p>Hello,</p>
<p>i Habe a problem with the beam view component. It doesn't show the elements as cross sections, it says: This object contains one error. </p>
<p>I have beams via the definition of the cross section container where I select my own diameter and thickness, but also tried the same profiles with list item from the cross section range selector, they are all standart profiles.</p>
<p>Does someone know why the beam view doesn't show the profiles?</p>
<p>Thanks in advance! </p>
