tidy3d.components.monitor.TimeMonitor#

class TimeMonitor[source]#

Bases: Monitor, ABC

Monitor that records data in the time-domain.

Parameters:
  • center (Attribute: center) –

    Type

    Tuple[float, float, float]

    Default

    = (0.0, 0.0, 0.0)

    Units

    um

    Description

    Center of object in x, y, and z.

  • size (Attribute: size) –

    Type

    Tuple[NonNegativeFloat, NonNegativeFloat, NonNegativeFloat]

    Default

    Units

    um

    Description

    Size in x, y, and z directions.

  • name (Attribute: name) –

    Type

    ConstrainedStrValue

    Default

    Description

    Unique name for monitor.

  • interval_space (Attribute: interval_space) –

    Type

    Tuple[Literal[1], Literal[1], Literal[1]]

    Default

    = (1, 1, 1)

    Description

    Number of grid step intervals between monitor recordings. If equal to 1, there will be no downsampling. If greater than 1, the step will be applied, but the first and last point of the monitor grid are always included. Not all monitors support values different from 1.

  • colocate (Attribute: colocate) –

    Type

    Literal[True]

    Default

    = True

    Description

    Defines whether fields are colocated to grid cell boundaries (i.e. to the primal grid) on-the-fly during a solver run. Can be toggled for field recording monitors and is hard-coded for other monitors depending on their specific function.

  • start (Attribute: start) –

    Type

    NonNegativeFloat

    Default

    = 0.0

    Units

    sec

    Description

    Time at which to start monitor recording.

  • stop (Attribute: stop) –

    Type

    Optional[NonNegativeFloat]

    Default

    = None

    Units

    sec

    Description

    Time at which to stop monitor recording. If not specified, record until end of simulation.

  • interval (Attribute: interval) –

    Type

    Optional[PositiveInt]

    Default

    = None

    Description

    Sampling rate of the monitor: number of time steps between each measurement. Set interval to 1 for the highest possible resolution in time. Higher integer values downsample the data by measuring every interval time steps. This can be useful for reducing data storage as needed by the application.
