I have a few suggestions. #1 For me it seems like the core structure seems pretty coars for such a simulation, I would suggest increasing the number of elements on this structure.
For this you can use a regional refinemet or a local element size
#2 As seen in the result control the core structure is penetrating the top layer. Therefore a physical contact needs to be defined between the bottom face of the top layer and the wally of the core pyramids.
Actually, for meshing I mainly focus on the faces of interest to save my core hours. The top and bottom face plate have little importance for the analysis and I want no data from these two regions.
To avoid rigid body motion I set remote displacement as BC, made the z axis unconstrained and the upper plate as undeformable. Isn’t that appropriate in this case?
The top faces of the pyramid and the upper plate are already in bonded contact if I again add physical contact that detects conflicting contact issues. In this case what is the appropriate contact, please let me know.
Indeed, I am writing in details because I have only 4 simulations left for my current plan that’s why I need to be sure before a final approach.
I was able to create a working case.
What I did is I chose the top surface as the master and the side surfaces of the pyramids as slave faces.
I kept the top faces of the pyramids as bonded contact.
I also refined the surfaces of the pyramid to improve the contact calculation.
This is the result I got.
Thanks for your reply.
In fact, in my geometry, there are 10 different bodies but after simulating, in the solution fields there I can see only 8 bodies. That’s why I could not hide the top plate. Is there any way out?
