Running Analysis
Execute structural analysis on your model.
Before Running Analysis
Ensure your model is complete:
- ✓ All members have sections assigned
- ✓ All members have materials assigned
- ✓ Sufficient supports to prevent rigid body motion
- ✓ At least one load is applied
Running the Analysis
- Click the "Run Analysis" button in the toolbar
- Wait for the analysis to complete
- Check the status message for success or errors
Analysis Status
- Success: Results are available to view
- Warning: Analysis completed with warnings (check messages)
- Error: Analysis failed (check error details)
Common Errors
Unstable Structure
The structure can move freely (mechanism). Solutions:
- Add more supports
- Check for disconnected parts
- Verify member connectivity
Missing Properties
Members are missing section or material. Solutions:
- Select members without properties
- Assign sections and materials
Singular Matrix
Mathematical instability. Common causes:
- Collinear nodes (members in a straight line with pin connections)
- Insufficient supports
- Zero-stiffness members
Analysis Settings
Configure analysis options:
- Analysis Type: Linear, P-Delta, or General
- Load Cases: Select which cases to analyse
- Tolerance: Convergence criteria for iterative methods
Performance
Large models may take longer to analyse. For best performance:
- Use a modern browser (Chrome, Firefox, Edge)
- Ensure a stable internet connection
