Properties

Name	Type	Description
`cellSize`readonlyoptional	`number`	Metres per cell. One by default, which makes a chunk eight metres across.
`ambient`readonlyoptional	`AmbientState`
`species`readonlyoptional	`readonly string[]`	Gas species to track. Twelve by default; a consumer may name fewer and pay less.
`maxChunks`readonlyoptional	`number`	How many chunks the live set may grow to before its edge becomes far field. More A plume growing the live set is correct — smoke really does reach new ground — and unbounded growth is not. Past the cap a boundary face vents to the ambient instead of creating a neighbour, which degrades a plume into a dissipating one rather than failing.
`openness`readonlyoptional	`number`	How fast an open boundary equalises with the far field, per second.
`diffusivity`readonlyoptional	`number`	Diffusivity between neighbouring cells, m²/s.
`reactions`readonlyoptional	`ReactionRegistry`	Where `reactionIds` are looked up.
`reactionIds`readonlyoptional	`readonly string[]`	Gas-phase reactions to run in every cell, by id. More `§8.4`'s combustion, and it is not a second implementation of the solver a shell uses — it is that one, given a cell. Which is what makes a flame stand off a surface rather than sit on it: burning is something the air does, in the place where the mixture is right.
