class AbstractAutoGrid[source]#

Bases: GridSpec1d

Specification for non-uniform or quasi-uniform grid along a given dimension.

Parameters:

max_scale (float = 1.4) – Sets the maximum ratio between any two consecutive grid steps.
mesher (GradedMesher = GradedMesher()) – The type of mesher to use to generate the grid automatically.
dl_min (Optional[NonNegativeFloat] = None) – [units = um]. Lower bound of the grid size along this dimension regardless of structures present in the simulation, including override structures with enforced=True. It is a soft bound, meaning that the actual minimal grid size might be slightly smaller. If None or 0, a heuristic lower bound value will be applied.
