Discretization#

`tidy3d.GridSpec`	Collective grid specification for all three dimensions.
`tidy3d.AutoGrid`	Specification for non-uniform grid along a given dimension.
`tidy3d.UniformGrid`	Uniform 1D grid.
`tidy3d.QuasiUniformGrid`	Similar to `UniformGrid` that generates uniform 1D grid, but grid positions are locally fine tuned to be snaped to snapping points and the edges of structure bounding boxes.
`tidy3d.CustomGrid`	Custom 1D grid supplied as a list of grid cell sizes centered on the simulation center.
`tidy3d.CustomGridBoundaries`	Custom 1D grid supplied as a list of grid cell boundary coordinates.
`tidy3d.Coords`	Holds data about a set of x,y,z positions on a grid.
`tidy3d.FieldGrid`	Holds the grid data for a single field.
`tidy3d.YeeGrid`	Holds the yee grid coordinates for each of the E and H positions.
`tidy3d.Grid`	Contains all information about the spatial positions of the FDTD grid.
`tidy3d.LayerRefinementSpec`	Specification for automatic mesh refinement and snapping in layered structures.
`tidy3d.GridRefinement`	Specification for local mesh refinement that defines the grid step size and the number of grid cells in the refinement region.
`tidy3d.CornerFinderSpec`	Specification for corner detection on a 2D plane.
