How to use Python scripts to make free-body force diagrams in Abaqus

Thank you for sharing this wonderful process of odb postprocessing

I am very happy to hear that! Thanks!

@@tecnodigitalschool However this process is not feasible when you try to use abaqus python, since abaqusModules cannot be imported in abaqus python. can you suggest something that facilitates this process in abaqus python?

Hi, thank you for sharing this. You explained it very nicely and in detail. I have a question, not exactly related to this but still you might have an idea. For a plugin I am writing, I am extracting section forces from bolt which i will use for safety calculations. However, the view cut (so body forces) should be aligned with bolt axis. How can i get bolt axis? Is there any easy way you are aware?

[@tecnodigitalschool]

You can define a surface (or set of faces) normal to the load axis and get the normal from it.

@@tecnodigitalschool thank you for quick answer! Do you know the method to get surface normal? I couldn't find it. I can probably get element face normal but surface would be much better.

[@tecnodigitalschool]

You can extract the normal from a face. If you have a surface, you can do the following: for face in p.surfaces["MySurface"].faces: print(face.getNormal()) Iterate through the faces of a surface and use getNormal.

Hello Sir, I tried to read data from Excel file using pandas. I did it the way you mentioned in the post, "How to use Python 3 with Abaqus and more". But abacus still shows no module named pandas. Even if we import certain libraries in "app.py" which aren't available in abacus, but still we can't incorporate those libraries in "abq.py". And as soon as we run app.py in python, abaqus shows there isn't any module named pandas. Please help me how to resolve this. Thank you

Hello Sanjeev, I guess you are referring to this blog post: tecnodigitalschool.com/how-to-use-python-3-with-abaqus-and-more/ If you run app.py within Abaqus it will fail, since the Python environment built into Abaqus does not include these Python 3 libraries (pandas, openpyxl, sklearn...). The script app.py is executed from an external Python 3 environment (kzbin.info/www/bejne/iXnGnn1maJ18gJo). This is the main script and will invoke (through the command line) Abaqus and run a second script (abq.py) that will include all the direct commands to control Abaqus. I hope this is useful for you! Best regards

@@tecnodigitalschool I need to pass the arguments from app.py to abq.py. Sir can you please share some part of script to do that. It will be of great help to me. Really need your help
