Convection: mixing-length theory

What you are seeing: the Schwarzschild criterion separates convective and radiative regions. Mixing-length theory parameterizes convective transport with α=lm/HP\alpha = l_m / H_P. Toggle the temperature-gradient excess to flip a layer between regimes.

WHAT TO TRY

  • Vary each control and watch the rail readouts respond.
  • Compare the diagnostic plot against the live scene.
