Detailed Description

Project a Finite Volume patch's data onto the overlap held on its surrounding faces, so the halo layers can be reconstructed from it later on -.

See also: toolbox.blockstructured.api.ReconstructPatchWithHalo.

Ported from the legacy python/exahype2/solvers/fv/actionsets/ProjectPatchOntoFaces.py, slimmed down: the legacy version additionally set the isUpdated()/ UpdatedTimeStamp() face metadata (read solver._face_label/solver._cell_label) so exahype2.solvers.fv.actionsets.RollOverUpdatedFace knew which half of a face had actually been written. The new exahype2.api's data structures (

See also: exahype2.api.fv.RusanovWithExplicitEuler) do not create a cell/face label yet, and RollOverUpdatedFace has not been ported either, so this version does purely what the base class toolbox.blockstructured.api.ProjectPatchOntoFaces already does: copy solver._patch's boundary layer into solver._patch_overlap_update. Once cell/face labels exist in the new API, the metadata-update behaviour can be reinstated here.

Constructor & Destructor Documentation

◆ init()

exahype2.api.fv.actionsets.ProjectPatchOntoFaces.ProjectPatchOntoFaces.__init__	(	self,
		patch,
		patch_overlap_update,
		guard,
		includes
	)

patch: peano4.api.datamodel.Patch The cell-associated patch to project onto its surrounding faces -

See also: exahype2.api.fv.RusanovWithExplicitEuler.

patch_overlap_update: peano4.api.datamodel.Patch The face-associated overlap patch to project patch's boundary layer into -

See also: exahype2.api.fv.RusanovWithExplicitEuler.

guard: str C++ boolean expression, evaluated per cell in touchCellLastTime, guarding whether that cell's patch is projected onto its faces.

includes: str Additional includes this action set's generated code needs - callers typically pass solver._get_default_includes() + solver.user_solver_includes.
