D command and nodal positions in ANSYS classic
D command and nodal positions in ANSYS classic
(OP)
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

RE: D command and nodal positions in ANSYS classic
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.
