@camierjs is this still an issue?

Hi @jtristano, can you provide some short code that does the setup and reproduces the issue?

@jtristano - I'd like to run the reproducer, but much of the code is missing. Try to provide a minimal reproducer. - You said hooke+NC+PA works, does it work in...

Hi @sungho91, what should the boundary nodes do in this case? (knowing that the initial boundary normals are generally discontinuous across the elements).

We have some ongoing work on such methods, but that is not ready yet. As I wrote above, the main challenge is that the tangential direction is not well-defined if...

Looks good, but if you detach the treatment of the boundary and the internal nodes, things can tangle quickly, especially with curved meshes.

Certainly, we can provide assistance by addressing specific questions and offering general guidance. However we won't have the availability to assist with actual code writing.
