Properties

bulk: number

Bulk modulus K of the equation of state, Pa. Sound speed is √(K·γ/ρ); real water's 2.2 GPa is far too stiff to step in real time.

density: number

Rest density, kg/m³.

gamma: number

Tait exponent γ: p = K·(J^−γ − 1). 7 for water; 1 is the linear law.

viscosity: number

Dynamic viscosity μ, Pa·s (τ += μ·J·(C + Cᵀ)). Real water is 0.001; a little more damps sloshing on a coarse grid.
