TAGGED: beams, Discovery AIM, shell, structures
April 7, 2020 at 7:34 amjunyi.leeSubscriber
Could you please advise on how to model beams and shells in AIM?
The only related information which I could find was the post below, where I am getting the same error message.
AIM is not able to mesh beams in a mixed model
The error message being: "Beams and/or shells have been detected. Select the modeling option and use shared topology to ensure the beam ends and shell edges are connected."
However, shared topology was used in SpaceClaim, contacts have been generated and the mesh could be generated.
The transcript reported the following error:
*** ERROR *** CP = 1.531 TIME= 14:41:56
A large negative pivot value ( -81.3586226 ) has been encountered in
the global assembled matrix at the ROTY degree of freedom of node 199.
This may be caused by a bad temperature-dependent material property
used in the model.
May I please know if there is a way to find the location of the aforementioned "node 199"? The material used was structural steel.

I'm looking into your model I will get back to you soon.

Upon investigating the model I noticed that there were issues with 'Share Topology'.
Once the topology is shared, you the assembly symbol in the Geometry tree changes as shown below.
Please find attached the edited model.🛈 This post originally contained file attachments which have been removed in compliance with the updated Ansys Learning Forum Terms & Conditions
