I am trying to "load" a quad element with prescribed displacements.
The command I have tried is:
pattern Plain 1 Linear{
sp 2 1 0.1
sp 3 1 0.1
}
This of course is intended to displace nodes 2 and 3 by 0.1 inches
in the x-direction.
All I get are blank output files when I try this.
Where is my error?

do you do more than just define the reference "loads", such as perform an analysis?
