Is there a way to export the position of the deformed gridpoints without having to manually calculate it from displacements?
In large-strain mode, the gp positions have included displacements.
In small-strain mode, we can run one-line FISH like
[gp.extra(::gp.list,1) ::= gp.pos(::gp.list) + gp.disp(::gp.list)]
then check FISH extra 1 for gridpoints.

I’m running a dynamic analysis in large‑strain mode. How can I extract the gp x‑displacement at the base of the model (e.g., at y = 0)? I need to subtract that value from the gp displacements to plot the relative displacement.
