Simulation of a 3D Beam Element in contact with a 3D Shell element
Simulation of a 3D Beam Element in contact with a 3D Shell element
(OP)
Hi everyone,
I’m trying to simulate a Wall solicited by a distributed load, supported by a Beam, as is presenting on the image (1):
Image 1

I created a 3D Beam Element to represent the beam, and a 3D Shell element to represent the wall. Then, I assignment the sections of each element and in the beam element I assign a beam orientation (Image 2):
Image 2

Them I made the assembly of the instances, apply the boundary conditions on the Beam and apply the load:
Image 3

To finish, I apply the tie constraint in the elements:
Image 4

The mesh, I made with the same seed size for the 3 elements.
There is something wrong in my model? Because the results were 15 X higher comparing with the model I made using solids elements. Do I made correctly the assign of the beam orientation? Could be the error the application of the tie constraint?

I'm attaching the .inp of the another model.

b) I strongly recommend not to run the shell model. Shell elements are not suitable for your situation. They are not good with in-plane loadings and bad ratio of thickness to edge length. Think about running the problem 2D (plane stress or plane strain) instead.

Do you think the interaction I made between the beam and shell element is good? I will think about running the problem 2D.
