Bases: NamedTuple

Return format for the time integration, when snapshots are requested.

angular_momentum: Array#

The angular momentum at the times the snapshots were taken.

current_checkpoint: int#

The current checkpoint, used internally.

num_iterations: int#

Number of timesteps taken.

runtime: float#

Alias for field number 4

states: Array#

The primitive states at the times the snapshots were taken.

times: Array#

The times at which the snapshots were taken.

total_energy: Array#

The total energy at the times the snapshots were taken.

odisseo.time_integration.time_integration(primitive_state: Array, mass: Array, config: SimulationConfig, params: SimulationParams)[source]#

Integrate the Nbody simulation in time. For the options of the time integration see the simulation configuration and the simulation parameters.

Parameters:

  • primitive_state – The primitive state array.

  • config – The simulation configuration.

  • params – The simulation parameters.

  • helper_data – The helper data.

Returns:

Depending on the configuration (return_snapshots, num_snapshots) either the final state of the fluid after the time integration of snapshots of the time evolution
