Numbering node abaqus
Numbering node abaqus
(OP)
Hello to everybody.
I'm working on Abaqus to develop a parametric study using an interface with SolidWorks and an optimization software. The point is that I've to change my abaqus model several times and Abaqus should mantein partition, force, boundary condition, etc. To do this I need to force some sets, that I've defined, to have always (duringe the several changing of the design of my part)the same number node when Abaqus remesh the part.
I hope I've explained good.
Any ideas?
Thanks in advance,
Jam3s

I'm very grateful for your reply, but can you explain better this idea?
I try to give you more details: I need to extract displacement (along three direction) of a point that I marked with a set. Meshing the part, Abaqus give a number to this set, using some rules that I don't discover yet. Next step is, in an automatic way, change part's geometry and when Abaqus remesh, it can happen that the same set is numbered with another number.
The problem is that I can use only the first .odb to train my software of optimization, and this sofware recognizes only node number and not set name. so if in firs .odd my set 'point' has number 30, if next time it will have number '31' I ca extract something non-sense.

What I propose is to export the 1 set of deformed coordinates to the *.dat file. The data will always be at the same location in the text file and Optimization programs have no issues finding it. I hope this helps.

I've had some problem with my internet connection.
During these days I've red the Abaqus documentation about scripting and I wrote a simple script that extract the information that I need to a .txt file. I think that this solution is the solution that you suggested me.
I think that without your advice, I didn't start to read that section of the documentation so I'm very grateful to you.
If I will encounter other problems I'll contact you again.
Thanks a lot,
