Balltracking - An ultra efficient method for tracking flow fields
3. Simulated granulation data
| Simulated granulation data (exaggerated velocity field)
|| Fourier filtered MDI data
The figure above shows a comparison of a small area of simulated granulation data and some filtered MDI data. The velocity field in the simulated data is about 5 times greater than that in the real data, in order to test the tracking method at high velocities. The simulated data has been spatially filtered in the same way as the MDI data.
