Save as beam_plugin.py in abaqus_plugins folder. 8. Best Practices & Common Pitfalls | Pitfall | Solution | |---------|----------| | Forgetting waitForCompletion() | Always call after submit() | | Hard-coded part names | Use variables or findAt() carefully | | Mixing mdb and session objects | Know the difference – mdb for model data | | Running GUI scripts in noGUI mode | Remove all session.viewport calls | | Not closing ODB files | Use odb.close() to avoid memory leaks |
Node label detection requires careful handling – in practice, use getClosest() on a set. 6. Example 4: Batch Post-Processing Multiple ODB Files Goal: Extract reaction force from many simulation results in a folder.
# Extract von Mises stress at fixed coordinates odb = openOdb(jobName + '.odb') frame = odb.steps['ApplyLoad'].frames[-1] stress = frame.fieldOutputs['S'] # Find stress at (length, 0) – tip tip_value = None for val in stress.values: if abs(val.nodeLabel - some_node_label) < 1e-3: # simplified tip_value = val.mises break results.append((size, tip_value)) odb.close() print("Mesh convergence data:", results)
