APDL Read List of Nodes from File and Select

[RealSaladsamurai]

Hi! I am awful at this. I am trying to write my first ANSYS 'code' and I am running into some issues. I have a CSV file that contains about 2000 node numbers. I would like to be able to select those nodes by reading the file. Is there a sensible way to do this? I have the following, but it's not working out:

/PREP7
*DIM,NTABLE,TABLE,25
*TREAD, NTABLE,test,csv
alls
nsel,r,,NTABLE(0)
*DO,i,1,25,1
nsel,a,,NTABLE(i)
*ENDDO
NPLO

The result is terrible and aw

The NSEL,r,,NTABLE(0) is not allowing the use of table the way I am trying. If anyone can help me get through this or offer an alternative method, I would be grateful.

2 things regarding OP: 1) I have no idea where that link came from ...sorry. 2) I am working on a subset of 25 nodes first. Thanks!

Any thoughts on this one?

You dont tell us the format of your csv file. Is it one node number per line?

You usually need to to assign values to the zeroth column, like this: *VFILL,ntable(1,0),ramp,1,1

I think your first nsel command should look like this: nsel,none

I think your second nsel command should look like this: nsel,a,node,,ntable(i)

I dont like tables in Ansys because I dont find them intuitive and I think the manual does a crappy job of explaining them. If you had a .txt file with one node number in each line, the following would work:

*DIM,NTABLE,,25
*vREAD,NTABLE(1),test,txt
(F12.0)
nsel,none
*DO,i,1,25
nsel,a,node,,NTABLE(i)
*ENDDO
Nlist
