Node Data From ODB

This Python script extracts node labels and coordinates from an Abaqus .odb file and saves the data in a readable text file. Developed initially out of curiosity, it simplifies node geometry extraction for FEA post-processing workflows.

Features

• Automatic ODB Detection: Finds and opens the first .odb file in the current directory.
• Node Data Export: Extracts node label and coordinates (X, Y, Z) for each instance.
• Clean Formatting: Saves organized node data into a human-readable text file.
• Skips Main Assembly: Ignores top-level "ASSEMBLY" instance for cleaner output.

Usage Instructions

1. Place this script in the same directory as your Abaqus .odb file.
2. Run the script using Abaqus CAE:

   abaqus cae noGUI=node_data_from_odb.py

3. The extracted node information will be saved to node_data.txt in the same directory.

Requirements

This script requires the following:

• Abaqus CAE (for accessing Abaqus Python API)
• Python 2.7 (used by Abaqus internally)
• win32com and subprocess (optional, included for Excel control)
