How to apply displacements that vary linearly

[sergini]

Ladys,Gents, Do you know how to apply displacements to one side of a model (for example sugar box model) which distribution is not uniform?? I would like to apply displacements that vary linearly from 0 mm at the base to 200 mm at the top.

Hi,

You need to use amplitude and assign it to your boundary condition.

In inputdeck the keyword will be look following:
...
*AMPLITUDE, NAME=move-XY
0.0, 0.0, 1.0, 1.0
*BOUNDARY, TYPE=DISPLACEMENT, AMPLITUDE=move-XY
node_id_to_move, 1, -200.0
...
