Enumeration Type Documentation

◆ cs_time_moment_restart_t

enum cs_time_moment_restart_t

Moment restart behavior.

Enumerator
CS_TIME_MOMENT_RESTART_RESET	Moment is reset in case of a restart file: starting time step will be no older than the restart time step.
CS_TIME_MOMENT_RESTART_AUTO	Moment uses restart information if available: if the requested time step is older than the restart time step, restart information will be used, though the starting time step is not guaranteed.
CS_TIME_MOMENT_RESTART_EXACT	If the requested time step is older than the restart time step, restart information will be used, and if the start time step or time does not match the one available, an error is thrown.

◆ cs_time_moment_type_t

enum cs_time_moment_type_t

Moment type.

Enumerator
CS_TIME_MOMENT_MEAN	Moment is a mean
CS_TIME_MOMENT_VARIANCE	Moment is a variance

◆ cs_time_moment_define_by_field_ids()

int cs_time_moment_define_by_field_ids	(	const char *	name,

		cs_time_moment_type_t	type,
		int	nt_start,
		double	t_start,
		cs_time_moment_restart_t	restart_mode,
		const char *	restart_name
	)

Define a moment of a product of existing field components.

Moments will involve the tensor products of their component fields, and only scalar, vector, or rank-2 tensors are handled (for post-processing output reasons), so a moment may not involve more than 2 vectors or 1 tensor, unless single components are specified.

If of dimension > 1, the moment array is always interleaved.

parameters: name <– name of associated moment n_fields <– number of associated fields field_id <– ids of associated fields component_id <– ids of matching field components (-1 for all) type <– moment type nt_start <– starting time step (or -1 to use t_start) t_start <– starting time restart_mode <– behavior in case of restart (reset, auto, or strict) restart_name <– if not NULL, previous name in case of restart

returns:

id of new moment in case of success, -1 in case of error.

Return the number of defined time moments.

		const char **	restart_name
	)

Define a moment restart mode and name by an id.

This is a utility function, to allow simplification of automatic setups. It must be called just before defining a moment to work properly if restart_id < -1 (automatic mode).

Parameters

[out]	restart_mode	matching restart mode
[out]	restart_name	matching restart name
