Hi Max, this looks like an interesting project.
I recommend using symmetry to reduce the size of the model to 1/4 of the whole. The symmetry boundary conditions will also help to support the model.
I looked at this webpage to learn about point-supported facades. Their panels are glass with holes where metal pins with shoulders and fasteners clamp the glass to the pins.
How do your glass-filled plastic pins contact the UHPC panel (shell)?Â
You say you embed the pins in the panel . Do you mean there is a blind hole in the panel where the pin is inserted?
You say the pin is 12 mm in diameter. What is the diameter of the hole in the panel ?
Are the pins bonded to the panel with an adhesive?
The answers to those questions will decide if you can model the panel using 3D shell elements meshing a sheet body, or if you have to use 3D solid elements meshing a solid body. If the pins go into a blind hole, then you must use solids.
Do the glass-filled plastic pins also go in holes in the support block?
What is the diameter of the holes in the support block?
What is the support block material?
Best regards,
Peter
