D command and nodal positions in ANSYS classic

[garycvv]

Hello,
I'm just checking a few of my assumptions when using the D command.
I'm trying to use the D command to apply displacements to some nodes. I assume that when I use the following command

D,1, ,-1, , , ,UX, , , , ,
This applies a displacement of -1 in the x-direction to node one. This displacement is relative to node's original position when the mesh was created.

If I then apply a second displacement to a different node such as fix node 2 -0.5 in the x-direction
D,2, ,-.5, , , ,UX, , , , ,
Will this move node 2 -0.5 from it's original position? Or from where it might be after node 1 has moved?
I've got the same question regarding listing nodal displacements, I've assumed these are relative to the nodes's original position, is this the case?
Thanks

Hello

Why don't you type D,1,UX,-1 ? Simpler, clearer, and using label1 instead of label2 (see the help on D command).

And yes, displacement applied from original position.
