Just as follow up in case people were interested,
I did get in contact with ABAQUS support team and this has been confirmed to be a bug. I will give another update once it is resolved
Thanks for your help!
Hello Igor,
Thank you for trying to assist me with this issue. So the input files are generated directly by custom software, so the GUI is only used for viewing the results. This means that the tangent directions are always the same for the two files (you can see that the node and beam element...
I've attached two pictures to this post that shows that the stress distribution and maximum stress do vary depending on whether you split the beam section definitions into 12 identical or just 1.
12 beam sections:
1 beam section:
Hi,
So the pictures of the beam orientations look identical for either case (as you would expect because the beam section definitions are identical).
That's why I'm thinking it has something to do with the nodal normals that is somehow introducing some twist into the beams. Unfortunately, I...
Hello all,
I am trying to model a cuboct lattice geometry using beam sections in ABAQUS.
I have noticed some strange behavior when modeling the geometry, depending on how I define my beam sections.
Each of my subunits that is used to build this lattice contains 6 nodes and 12 beams. I am...
