Selecting Nodes From VGET Vector
Folks,
I wrote a short script to form a vector with *VGET, *VOPER, and *VMASK of all nodes at a certain temperature. Is there a way to then select those nodes for display? In other words, I am wondering if there is any sort of NSEL syntax that will read the vector I made with VGET, so those nodes can be selected. Then I intend to do other operations downstream with those selected nodes.

I haven't tried this, but there is a *GET, *VGET item for whether a node is
selected or not. (item1=NSEL). You could try doing a *VPUT (-1=unselected,
1=selected). See if that actually changes the selection status of your
nodes.

Dear Mr. Ridzon,
what about this primitive way?
nsel,none
*do,i,1,yourvectorlength
*if,i,eq,1,then
nsel,,,,yourvector(i,n)
*endif
nsel,a,,,yourvector(i,n)
*enddo
That's provided the node numbers are stored in your vector's n-th column.

Or you might try using vector notation on the NSEL command, something like:
*GET,N,NODE,,NUM,MAX
*DIM,MASK,ARRAY,N
…
*VGET and *VOPER commands to flag the nodes in the MASK vector which are at the desired temperature
NSEL,S,NODE,,MASK(1:N)

Thanks for the feedback! Unfortunately, the node numbers are not stored in the n-th column. That was the crux of my issue. I really wish the *V--- commands gave that option.
I'm going to see if one of the ideas from the other contributors might work.

*VPUT #
*VPUT, ParR, Entity, ENTNUM, Item1, IT1NUM, Item2, IT2NUM, KLOOP
To change selection status of entities, use a format similar to *VGET.
Use for Entity = node, elem, kp, line, area, or volu, ENTNUM = 1, and Item1
= nsel, esel, ksel, lsel, asel, or vsel. The array ParR would be similar to
the *VGET array, where
-1 = unselected
0 = undefined
1 = selected
It is recommended to select all entities with nsel,all (or related command)
prior to using *VPUT.
