Probe viscoelastic properties through Brownian motion analysis
Pure viscous fluid — G' ≈ 0, only viscous dissipation
G' (Storage) @ 1 rad/s
0.000 Pa
G'' (Loss) @ 1 rad/s
0.001 Pa
|η*| (Complex Viscosity)
0.001 Pa·s
Ï„ (Relaxation Time)
— s
📋 Understanding the Simulation:
- Top-left: Trapped bead showing Brownian motion (diffusion changes with medium)
- Top-right:
G'(ω) and G''(ω) — storage and loss moduli vs frequency
- Bottom-left: Mean Square Displacement (MSD) — slope indicates diffusion behavior
- Bottom-right:
|η*(ω)| — complex viscosity vs frequency
- Try switching between Newtonian (water) and viscoelastic (polymer/gel) media!
