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__()

def 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.

add_tracer()

def CCZ4Solver.CCZ4Solver_FD4_GlobalAdaptiveTimeStepWithEnclaveTasking.add_tracer	(		self,
			name,
			coordinates,
			project,
			number_of_entries_between_two_db_flushes,

    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.

    @param project: exahype2.Project

    @param tracer_unknowns: Integer
      You can set this variable to None. In this case, all variables are
      dumped.

Reimplemented from CCZ4Solver.AbstractCCZ4Solver.
