Detailed Description

CCZ4 solver using fourth-order finite differences and global adaptive time stepping without enclave tasking.

Constructor & Destructor Documentation

__init__()

CCZ4Solver.CCZ4Solver_FD4_GlobalAdaptiveTimeStep.__init__	(		self,
			name,
			patch_size,
			rk_order,
			min_meshcell_h,
			max_meshcell_h,
			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.
