Detailed Description

Roll over the face data, and set the ghost volumes along the domain boundary through exahype2.api.SommerfeldBoundaryConditions first.

The action set replaces exahype2.api.fv.actionsets.RollOverUpdatedFace if the solver uses Sommerfeld boundary conditions. Such a solver has no separate boundary task (exahype2.api.fv.actionsets.ApplyDirichletBoundaryConditions). In touchFaceLastTime(), the action set first writes the ghost volumes into the ghost half of patch_overlap_update, and then rolls over both halves into patch_overlap_current_time_step like RollOverUpdatedFace. Faces within the domain and faces along periodic axes are rolled over unchanged. There are two variants:

With a time_step_size, the action set advances the ghost volumes through exahype2::blockstructured::applySommerfeldBoundaryConditions(). patch_overlap_current_time_step still holds the old solution, i.e. both its halves are valid, and patch_overlap_update holds the new interior solution. The time step uses this variant.
Without a time_step_size, the action set initialises the ghost volumes with the initial condition, i.e. it evaluates the solver's initPointWisely() at their centres through exahype2::blockstructured::applyDirichletBoundaryConditions(). The grid construction uses this variant, so the first time step finds valid ghost volumes.

The C++ header documents the conditions, their discretisation and why they replace the roll over.

Member Function Documentation

◆ create_roll_over()

exahype2.api.fv.actionsets.RollOverUpdatedFaceWithSommerfeldBoundaryConditions.RollOverUpdatedFaceWithSommerfeldBoundaryConditions.create_roll_over	(	solver,
		exahype2_project,
		guard,
		includes,
		time_step_size = `None`
	)

static

Create the roll over of the solver's face data.

Returns: RollOverUpdatedFace RollOverUpdatedFaceWithSommerfeldBoundaryConditions if the solver uses exahype2.api.SommerfeldBoundaryConditions, and a plain RollOverUpdatedFace otherwise, i.e. for Dirichlet boundary conditions or a domain without boundary.

Parameters

solver	exahype2.api.Solver The solver whose solver._patch_overlap_update is rolled over into solver._patch_overlap_current_time_step. Its boundary condition terms have to be consistent with the domain, exahype2.api.blockstructured.BoundaryConditions.get_boundary_conditions().
exahype2_project	exahype2.api.Project Provides the periodic boundary conditions.
guard	str

See also: RollOverUpdatedFace.

Parameters

includes str

See also: RollOverUpdatedFace.

Parameters

time_step_size str

See also: the constructor. Ignored for a plain RollOverUpdatedFace.

◆ get_action_set_name()

exahype2.api.fv.actionsets.RollOverUpdatedFaceWithSommerfeldBoundaryConditions.RollOverUpdatedFaceWithSommerfeldBoundaryConditions.get_action_set_name ( self )

Return unique action set name.

Returns a description (word) for the mapping which is also used as class name for the generated type. As a consequence, the result should be one word (if possible) and uppercase. Also, every subclass should overwrite this routine.

The generator will take the result and construct eventually classes similar to MyStep2Dummy.h and MyStep2Dummy.cpp or similar for the example below, where we return Dummy.

◆ get_body_of_operation()

exahype2.api.fv.actionsets.RollOverUpdatedFaceWithSommerfeldBoundaryConditions.RollOverUpdatedFaceWithSommerfeldBoundaryConditions.get_body_of_operation	(	self,
		operation_name
	)

Return actual C++ code snippets to be inserted into C++ code.

See class' string constants starting with OPERATION_ for possible values of operation_name. The snippet is executed if and only if the guard returned by get_guard_of_operation() holds, i.e. the body should not evaluate the guard itself. See the section "Guard and body" in the class documentation.

◆ get_includes()
