tidy3d.CustomGrid

class tidy3d.CustomGrid

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

Parameters

dl (Tuple[PositiveFloat, ...]) – [units = um]. 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). Note: if supplied sizes do not cover the simulation size, the first and last sizes are repeated to cover the simulation domain.

Example

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

attribute dl: Tuple[pydantic.types.PositiveFloat, ...] [Required]

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). Note: if supplied sizes do not cover the simulation size, the first and last sizes are repeated to cover the simulation domain.
