aquakin.TrackSolution

class aquakin.TrackSolution(t, C, model)

Bases: _HasNamedSpecies, PlottableSolutionMixin, ExportableSolutionMixin

Solution returned by ParticleTrackReactor.solve().

C (shape (n_t, n_species)) is the raw integrated state. If the model sets clip_negative_states, entries may be small transient negatives – the max(C, 0) clamp is applied only when evaluating the reaction rates, not to the saved state. A normal numerical transient, not an error; clip with jnp.maximum(sol.C, 0.0) for display if needed.

Parameters:

• t (Array)

• C (Array)

• model (CompiledModel)

__init__(t, C, model)

Parameters:

• t (Array)

• C (Array)

• model (CompiledModel)

Return type:

None

Methods

C_named(species)	Return the trajectory of a single species by name.
C_named_many(species)	Trajectories of several species by name, as {name: array}.
__init__(t, C, model)
final_named([species])	Values at the last recorded point, as {name: float}.
plot([species, ax])	Plot one or more species against the independent axis (time, or axial position for a PFR).
to_csv([path_or_buf, units_in_columns])	Write the solution to CSV (delegates to to_dataframe()).
to_dataframe(*[, units_in_columns])	Return the solution as a pandas DataFrame.
units_named(species)	Return the declared units of a species (for axis/column labels).

Attributes

final	Every species' value at the last recorded point ({name: float}).
time_unit	The time unit of self.t ("s", "d", .
