Support Motion

Hi,

I’m trying to perform a linear time history analysis on a simple model and as loading I would like to define the motion over time of the supports.
I’m using ASE as I have no access to DYNA, so I’m not sure if this is possible.
Essentially I’m wondering if there is an input similar to ACCE in ase but instead of acceleration I would like to define the actual movement in time of the supports.

Thanks.

Define a spring of high stiffness (1E20) at node you want to load with support displacement then define load function with high force causing spring dispacement equal to your disp*1E20.
