warp.fem.adaptive_nanogrid_from_hierarchy(
grids,
grading=None,
temporary_store=None,
)[source]#

Constructs a warp.fem.AdaptiveNanogrid from a non-overlapping grid hierarchy.

Warning: The result is undefined if there are partial overlaps between levels, that is if a cell at level l is only partially covered by cells at levels l-1 or lower.

Parameters:

  • grids (list[Volume]) – List of sparse Volumes, from finest to coarsest

  • grading (str | None) – Supplementary grading condition, may be None, “face” or “vertex”; see enforce_nanogrid_grading()

  • temporary_store (TemporaryStore | None) – Storage for temporary allocations

Return type:

AdaptiveNanogrid
