How to apply displacements that vary linearly

How to apply displacements that vary linearly

How to apply displacements that vary linearly

(OP)
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.

RE: How to apply displacements that vary linearly

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
...

Regards,
Bartosz
