While searching for a way to enter a node-to-node spring, I found an APDL method.

I tried to create a node using Spring > Commands (APDL), but it didn't work as intended, so I am looking for another method.

n, a, x1, y1, z1

n, b, x2, y2, z2

e, a, b

However, it does not seem to be working properly. Could you please help me?

Additionally,

I have a CSV file containing X, Y, and Z coordinates, and I want to connect springs between pairs that have the same X and Y coordinates but different Z coordinates.

ex) 1, 1, 1

1, 1, 2

2, 2, 1

2, 2, 2

...

I want to create nodes at these coordinates and connect them with springs. If anyone knows how to do this, please let me know.

Thank you.
