tidy3d.CustomGrid#

class CustomGrid[source]#

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), 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 (Optional[float] = None) – [units = um]. 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])
