hello

I am working with modeling software CAESAR II, a pipeline mounted on a mobile rack (movement of the earthquake) I want to model a support mounted on a rack with a displacement (X = +-30mm, Y = +-50mm ,Z (vertical) = 0mm).
is that true to make as the following?:
support node 40 (with Z + restarint CNOD 2040) and the three displacement vectors V1 (Dx = 30, remains free (empty)
V2 (Dy = 50, remains free
V3 (Dz = 0, remains free

thank you for advance
