Hi @DaleKramer,
I try to avoid the symmetry BC as it sometimes can lead to numerical troubles together with other BCs on shared nodes. So as long as the faces which I want to put a symmetry BC on are orthogonal to one of the coordinate axes I tend to use an equivalent fixed value BC and only use the symmetry BC if this can’t be used e.g the surface normal is not aligned with any of the axes.
The half space geometry primitive can not be used for anything explicitly - it is used to define the half space for the mesh clip.
still with the remote displacement on the node - now only constraining Z.
Sorry, I wanted to say “nose” instead of “node”.
Best,
Richard
