• Vorticity
• Q-value
• Tracer particles

Parameters

By default the Rayleigh and the Prantdl numbers are set to 8.5e7 and 4.4e0, respectively. Two URL parameters ra and pr are available to change them, e.g.: https://naokihori.github.io/WebNSSolver/index.html?ra=1.0e8&pr=0.25.

The minimum / maximum Rayleigh numbers are 1.0e+4 / 4.0e+8. The minimum / maximum Prantdl numbers are 1.0e-1 / 1.0e+1.
