# 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
