Thanks Richard.
Your constraints still confuse me.
You don’t seem to have a symmetry plane boundary condition at all, you simply constrain the faces on what should be a symmetry plane such that the faces can not move off that plane. What is the purpose of the ‘Symmetry plane’ boundary condition if you don’t really need to use it? Also, what is the geometry primitive ‘Half space’ used for?
Also, your ‘Remote displacement 3’ acts on faces, not nodes as you suggest above.
I will keep trying.
