RH2ABA: Automated IGES Import and Assembly in Abaqus

This project provides a Python-based solution for importing multiple .iges files (developed via visual programming) into Abaqus, creating parts, generating assembly instances, and adding a reference point based on coordinates from a text file (which depends on the loading joint socket of the hydraulic jack). It automates repetitive tasks and ensures consistent setup for Abaqus simulations.

Features

• Automated IGES Import: Detects all .iges files in the directory and imports them into Abaqus.
• Wire and Solid Detection: Automatically detects reinforcement/wire components (e.g., stirrups, ties, long bars) based on filename keywords.
• Part Creation: Creates Abaqus parts from IGES geometry with configurable settings for solid or wire parts.
• Assembly Instances: Generates independent instances of each part in the assembly for further modeling.
• Reference Point Import: Reads coordinates from a text file and creates a reference point in the assembly.
• Viewport Setup: Optimizes viewport display for quick visualization of parts and assembly.

Usage Instructions

1. Clone or download the repository: RH2ABA.
2. Place your .iges files in the same directory as the script.
3. Create a text file Socket Joint Coordinates.txt containing the x, y, z coordinates for the reference point (in a single line, e.g., {0.0, 10.5, 5.2}).
4. Run the script inside Abaqus CAE using the Python interpreter embedded in Abaqus:

   abaqus cae noGUI=RH2ABA.py

5. The script will:
   • Create a fresh model database.
   • Import all IGES files as parts.
   • Create assembly instances of each part.
   • Add the reference point at the specified coordinates.
   • Display messages confirming success for each step.

Example Files

• Included in the repository are example .iges files demonstrating solid and wire geometries.
• The Socket Joint Coordinates.txt example file shows how to provide coordinates for the reference point.
• All generated parts and assembly variations can be opened directly in Abaqus CAE.

Requirements

The script requires:

• Abaqus with Python scripting enabled.
• Python standard libraries: os, glob, re.

No additional packages are required since it uses Abaqus CAE modules.
