I've been using Abaqus for a while but I'm new to macros and python script. I'm sorry if this kind of question has already been asked, I did search on google to see if there was a similar problem but nothing works..

My problem is the following :

I have a model in Abaqus, I've ran an analysis with 2 steps and I created a path in it and I'd like to extract the value of the Von Mises stress along this path for each frame of each step. Ideally I'd love to save it into an Excel or a .txt file for easy further analysis (e.g in Matlab).

Edit : I solved part of the problem, my macro works and all my data is correctly saved in the XY-Data manager.

Now I'd like to save all the "Y" data in an excel or text file and I have no clue on how to do that. I'll keep digging but if anyone has an idea I'll take it !

Here's the code from the abaqusMacros.py file :
