Reply To: Input displacement of all surface nodes for a model

[peteroznewman]

You have a text file with 2000 rows of data in the format:
node_ID, Xu, Yu, Zu
for the coordinates of the undeformed surface nodes.
You also have a text file with the same 2000 rows of data in the same format:
node_ID, Xd, Yd, Zd
for the deformed coordinates of the surface nodes.
Put those two files side-by-side in 8 columns of a spreadsheet and in the next three columns calculate the deformation as:
Dx = Xd - Xu
Dy = Yd - Yu
Dz = Zd - Zu
