use surface-to-surface

Hi Chase Mortensen,

surface to surface contact is necessary or use general contact for your model.

If you have assigned contact between the platen and the core, it could be a graphical error and there is no worry about the simulation. @

It sounds like you are experiencing issues with penetration between your corrugated core and rigid platen in a quasi-static compression simulation. One potential solution to this issue could be to adjust the contact properties between the core and platen. You could try increasing the stiffness of the contact or using a different contact algorithm to prevent penetration.

Another approach could be to refine the mesh of your model to improve the accuracy of the simulation. This could help to reduce penetration by providing a more detailed representation of the contact between the core and platen.

It’s also possible that the issue is related to the way you have defined the interaction between the core and platen. You mentioned that you are using a node-to-surface interaction with the master being the platen and the secondary being the nodes along the top and bottom of the core. You could try experimenting with different interaction definitions, such as using a surface-to-surface interaction, to see if this helps to reduce penetration.

I hope these suggestions are helpful! Let me know if you have any further questions or concerns.

Chase Mortensen, the surface to surface interaction with smaller slave surface mesh density will solve the problem. For more, let's connect on WhatsApp to discuss; https://wa.me/+923440907874
