Warm simulation note

  • This is the second simulation after the isothermal baseline.
  • It adds compressible warm gas at 400 K without jumping to 700 C.
  • The run completed cleanly to 0.08 s.
  • Next increase is 500 K, then buoyant gravity, then masonry coupling.

What this says

  • The gas volume is connected and solvable.
  • The lower collector/path is the fastest active route.
  • Both side towers participate in the preview flow.
  • Left/right balance is acceptable for a first geometry pass, around 10% mean-speed delta.

What is still missing

  • Buoyant hot gas is not stable yet.
  • The buoyancy attempt collapses timestep near 0.00038 s and fails in correctBuoyantPressure.
  • This is not masonry heat storage yet.
  • Next useful improvement is a smaller buoyant validation case, then CHT.
