# 2: Extracting field output from Tube hydroforming odb file by python scripting in Abaqus

This video is the second part of a series which explain Inverse finite element modeling (FEM) of tube hydroforming by Python scripting in Abaqus. In this video extracting displacement from odb file by python scripting in Abaqus is explained. In next videos of this series, finding appropriate pressure for obtaining desired dimeter of tube by python scripting will be explained. In this video you can find out:
How to open an odb file and put it in a variable?
How to find exact value of a field output in a node?
How to extract field outputs like displacement, strain, stress, … at a node by Python scripting?
How to show node labels?
How to find the index of a node in Python list?
ff = session.openOdb(name='Hydro.odb')
u = ff.steps['Step-1'].frames[-1].fieldOutputs['U'].values[92].data

Thank you, the video is really helpful

Keep Up , very nice videos

Hello, thanks for this video ! u = ff.steps['Step-1'].frames[-1].fieldOutputs['U'].values[92].data , here , how do i know that the index 92 is for a node and not for an element ?

Hi Dear,
I have a problem, I prepared a code to open an ODB file. I want to get stress, strain, and strain in a layer of mesh or in a path when the nodes in that layer or path reach a certain temperature (for example 520 C), so data was not at the same time.
I want to know how can I define a path or layer of nodes in my model in the python code? and generally, do you have any solution or idea for this problem.

For extracting data across special path you should create a node set before running your model. After opening the odb file, At first you should find the frame number by checking the temp of that point across all frames. Then find the values in the frame based on set name.

Dear Sir, How can we find the average of frame values instead of last values? Kindly help!

[@engineering_software]

You should use a for loop over all frames and calculate the average.

[@AdarshKumar-xf6kb]

@@engineering_software Okay Sir. Thank you very much!

Hi, is there any videos step by step for simulation of tube hydroforming
