`salvus.mesh.layered_meshing.meshing_protocol.coarsening_policy.compute_coarsening_policies`

Utility function to compute coarsening policies.

Functions

`compute_coarsening_policies()`

def compute_coarsening_policies(
    domain: _domain.Domain,
    layered_model: _layered_model.LayeredModel,
    mesh_resolution: types.MeshResolution,
    coarsening_policy: InterlayerCoarseningPolicy = InterlayerDoubling(
        n_layers="auto"
    ),
) -> list[InterlayerCoarseningPolicy]: ...

Compute coarsening policies for meshing a layered model.

This function determines the coarsening policies for a given layered model based on the domain, mesh resolution, and an optional interlayer coarsening policy. It evaluates the minimum layer thickness and the maximum element size reduction across layers to decide the appropriate coarsening strategy.

Parameters

domain _domain.Domain — The domain object representing the spatial domain of the mesh.
layered_model _layered_model.LayeredModel — The layered model object containing the mesh layers and their properties.
mesh_resolution types.MeshResolution — The resolution of the mesh, which influences the element size and coarsening decisions.
coarsening_policy InterlayerCoarseningPolicy — The default interlayer coarsening policy to use. Defaults to InterlayerDoubling().

Returns list[InterlayerCoarseningPolicy] — A list of coarsening policies for the layers, determined based on the computed thickness-to-element size ratio.
