NavierStokesModifiedRestartSolution

class NavierStokesModifiedRestartSolution

Bases: FluidInitialCondition

Attributes

constants: dict[str, str], optional

Named constants or reusable sub-expressions that the initial condition expressions may reference. Like the expressions themselves, these carry no units and are nondimensional.

Default:

None

rho: str

Density

Default:

'rho'

u: str

X-direction velocity

Default:

'u'

v: str

Y-direction velocity

Default:

'v'

w: str

Z-direction velocity

Default:

'w'

p: str

Pressure

Default:

'p'

species_mass_fractions: dict[str, str], optional

Optional initial mass-fraction expressions of (x, y, z), keyed by species name; an expression is required for every declared species and zero values are legal. Values are projected onto the simplex (clamped non-negative and normalized to sum to one) at each node. When omitted, the initial composition is the uniform reference mixture. Requires a SpeciesTransportSolver and a Gas with two or more species.

Default:

None
