Hello, I need your help with a model. I want to model a polystyrene nanoparticle (d=20 nm) in water on Comsol.
- What are the vibration effects?
- The medium should be water.
- The excitation type is opto-thermal/light excitation.
- Particle point/average displacement vs. time.
- Maximum RMS displacement vs. time.
- Q-factor / damping extraction.
- Pressure field p(x,t) in fluid.
- Fourier transform (FFT) of pressure/potential time series → spectrum.
- Mode shape snapshots (in time or from modal analysis).
- Acoustic energy flow / power.
- Phase vs. time or vs. frequency
- Parameter scans (sensitivity plots)
- Spatial cross-sections / field maps (p(x,t) or u(x,t))
- If optothermal: Temperature(t) at particle & fluid + thermoelastic stress.
How do I model these and visualize the vibration and time-dependent relationships in graphs? Thank you very much for your help...
