💡 Tips

Be selective with Output Fields to manage file sizes
Use Time-Averaged outputs for statistical analysis of unsteady flows
For large meshes, consider using Slice or Surface outputs instead of Volume outputs
For better performance, limit output frequency to necessary intervals

❓ Frequently Asked Questions

How can I visualize vortices in my flow?

Use Volume Output with Q-criterion field or create dedicated Isosurface Output of Q-criterion.
What’s the difference between Surface Output and Surface Probe Output?

Surface Output captures data across entire surfaces, while Surface Probe Output captures data at specific points on surfaces.
Can I save outputs in different formats?

Yes, you can choose between Paraview (.vtu, .vtp), Tecplot (.szplt), or both formats.
