Detailed Description

CCZ4 solver using fourth-order finite differences and global adaptive time stepping incl enclave tasking.

The constructor of this classs is straightforward and realises the standard steps of any numerical implementation of the CCZ4 scheme:

1. Init the actual numerical scheme. This happens through the constructor of the base class.
2. Add the header files that we need, i.e. those files which contain the actual CCZ4 implementation.
3. Add some constants that any CCZ4 C++ code requires.
4. Set the actual implementation, i.e. link the generic PDE terms to the CCZ4-specific function calls.
5. Add the CCZ4-specific postprocessing.
6. Switch to higher-order interpolation and restriction.

Constructor & Destructor Documentation

__init__()

CCZ4Solver.CCZ4Solver_FD4_GlobalAdaptiveTimeStepWithEnclaveTasking.__init__	(		self,
			name,
			patch_size,
			rk_order,
			min_meshcell_h,
			max_meshcell_h,
			pde_terms_without_state,
			second_order = False )

Constructor.

Calibrate the default time step size calibration with 1/16 to take into account that we have a higher-order numerical scheme.

Member Function Documentation

add_tracer()

CCZ4Solver.CCZ4Solver_FD4_GlobalAdaptiveTimeStepWithEnclaveTasking.add_tracer	(		self,
			name,
			coordinates,
			project,
			number_of_entries_between_two_db_flushes,
			data_delta_between_two_snapsots,
			time_delta_between_two_snapsots,
			clear_database_after_flush,
			tracer_unknowns )

Add tracer to project.

This is a delegate to add_tracer_to_FD4_solver() which passes the object in as first argument.

Consult exahype2.tracer.DumpTracerIntoDatabase for an explanation of some of the arguments. Most of them are simply piped through to this class.

Parameters

project	exahype2.Project
tracer_unknowns	Integer You can set this variable to None. In this case, all variables are dumped.

Reimplemented from CCZ4Solver.AbstractCCZ4Solver.
