I am modeling a composite bridge on ANSYS APDL.
i modeled the deck slab as a brick solid element and I had to divide it into 7 parts for the meshing to work (attached).
After meshing all elements in my model, I merged the nodes with 0.001 tolerance.
But then I got these two errors (attached).
Unfortunately, this error affects my model connectivity as when I add my boundary conditions, the model is still considered as insufficiently restrained.
