! Boundaries

Boundary Condition 1
Name = "symmetry"
Target Boundaries(1) = 2
Periodic BC = Integer 2
Periodic BC Translate(3) = Real 0 0 0
Periodic BC Rotate(3) = Real 0 0 90
Periodic BC Scale(3) = Real 1 1 1
Periodic BC Displacement = Logical True
End

Boundary Condition 2
Name = "target"
Target Boundaries(1) = 3
Displacement 1 = 0 ! Normal in Cartesian
End

Boundary Condition 3
Name = "shaft"
Target boundaries (1) = 1
Displacement 2 = 0
Displacement 3 = 0
Normal-Tangential Displacement = Logical True
End
