tidy3d.CustomGrid#

class CustomGrid[source]#

Custom 1D grid supplied as a list of grid cell sizes centered on the simulation center.

Parameters:

dl (Attribute: dl) –

`Type`	Tuple[PositiveFloat, …]
`Default`
`Units`	um
`Description`	An array of custom nonuniform grid sizes. The resulting grid is centered on the simulation center such that it spans the region `(center - sum(dl)/2, center + sum(dl)/2)`, unless a `custom_offset` is given. Note: if supplied sizes do not cover the simulation size, the first and last sizes are repeated to cover the simulation domain.

custom_offset (Attribute: custom_offset) –

`Type`	Optional[float]
`Default`	= None
`Units`	um
`Description`	The starting coordinate of the grid which defines the simulation center. If `None`, the simulation center is set such that it spans the region `(center - sum(dl)/2, center + sum(dl)/2)`.

Example

>>> grid_1d = CustomGrid(dl=[0.2, 0.2, 0.1, 0.1, 0.1, 0.2, 0.2])
