Checkpointing

The following inputs must be preceded by “mfix.” and control checkpoint/restart.

	Description	Type	Default
restart	If present, then the name of file to restart from	String	None
check_int	Frequency of checkpoint output in timesteps number; if -1 then no checkpoints will be written	Int	-1
check_per_approx	Frequency of checkpoint output in simulation time; if 0 then no checkpoints will be written	Real	0
check_walltime_interval	Frequency of checkpoint output in runtime (HH:MM:SS)	String	“”
check_file	Prefix to use for checkpoint output	String	chk
geom_chk_write	When True, writes the EB geometry data into geom_chk_file and additionally, geom_refined_chk_file, if levelset refinement is enabled.	bool	False
geom_chk_read	When True, reads the EB geometry data from geom_chk_file and additionally, geom_refined_chk_file, if levelset refinement is enabled.	bool	False
geom_chk_file	Name of the EB checkpoint file that is used to store or read the unrefined geometry.	String	geom_chk
geom_refined_chk_file	Name of the EB checkpoint file that is used to store or read the refined geometry, i.e. when levelset refinement is enabled.	String	geom_ refined_ chk
