Function Documentation

cs_restart_read_bc_coeffs()

void cs_restart_read_bc_coeffs

(

cs_restart_t *

r

)

Read boundary condition coefficients for all fields from checkpoint.

Parameters

[in,out]

r

associated restart file pointer

cs_restart_read_field_info()

void cs_restart_read_field_info	(	cs_restart_t *	r,
		cs_map_name_to_id_t **	old_field_map
	)

Read field metadata from checkpoint.

Old ids associated to each field are determined for future use. Note that when reading legacy files (Code_Saturne version 3.3 and below), the old id will actually be the old scalar id (-1 for others).

Parameters

[in,out]	r	associated restart file pointer
[out]	old_field_map	name to id map of fields in restart file

cs_restart_read_field_vals()

int cs_restart_read_field_vals	(	cs_restart_t *	r,
		int	f_id,
		int	t_id
	)

Read field values from checkpoint.

If the values are not found using the default rules based on the field's name, its name itself, or a "restart_rename" keyed string value, an old name may be used for compatibility with older files. For cell-based fields, the old name base is appended automatically with "_ce_phase01", except for scalars, where the name uses a different scheme, based on "scalaire_ce_%04" % s_num;

Parameters

[in,out]	r	associated restart file pointer
[in]	f_id	field id
[in]	t_id	time id (0 for current, 1 for previous, ...)

Returns

CS_RESTART_SUCCESS in case of success, CS_RESTART_ERR_... otherwise

cs_restart_read_fields()

void cs_restart_read_fields	(	cs_restart_t *	r,
		cs_restart_file_t	r_id
	)

Loop over all fields and read them in the restart file which id is passed in argument if it matches their "restart_file" key value.

Parameters

[in,out]	r	associated restart file pointer
[in]	r_id	value of the key "restart_file"

cs_restart_read_linked_fields()

void cs_restart_read_linked_fields	(	cs_restart_t *	r,
		const cs_map_name_to_id_t *	old_field_map,
		const char *	key,
		int	read_flag[]
	)

Read fields depending on others from checkpoint.

Old ids associate to each field are determined for future use. Note that when reading legacy files (Code_Saturne version 3.3 and below), the old id will actually be the old scalar id (-1 for others).

Parameters

[in,out]	r	associated restart file pointer
[in]	old_field_map	name to id map of fields in restart file
[in]	key	key for field association
[in,out]	read_flag	optional flag to track fields read, or NULL; set to sum of 2^time_id for fields read, -1 for fields failed to read (size: n_fields)

cs_restart_read_time_step_info()

void cs_restart_read_time_step_info

(

cs_restart_t *

r

)

Read restart time step info.

Parameters

[in,out]

r

associated restart file pointer

cs_restart_read_variables()

void cs_restart_read_variables	(	cs_restart_t *	r,
		const cs_map_name_to_id_t *	old_field_map,
		int	t_id_flag,
		int	read_flag[]
	)

Read variables from checkpoint.

Parameters

[in,out]	r	associated restart file pointer
[in]	old_field_map	name to id map of fields in restart file
[in]	t_id_flag	-1: all time values; 0: current values; > 0: previous values
[in,out]	read_flag	optional flag to track fields read, or NULL; set to sum of 2^time_id for fields read (size: n_fields)

cs_restart_write_bc_coeffs()

void cs_restart_write_bc_coeffs

(

cs_restart_t *

r

)

Write boundary condition coefficients for all fields to checkpoint.

Parameters

[in,out]

r

(

cs_restart_t *

r

)

Write field metadata to main checkpoint.

Parameters

cs_restart_write_field_vals()

void cs_restart_write_field_vals	(	cs_restart_t *	r,
		int	f_id,
		int	t_id
	)

Write field values to checkpoint.

Parameters

[in,out]	r	associated restart file pointer
[in]	f_id	field id
[in]	t_id	time id (0 for current, 1 for previous, ...)

cs_restart_write_fields()

void cs_restart_write_fields	(	cs_restart_t *	r,
		cs_restart_file_t	r_id
	)

[in]	r_id	value of the key "restart_file"

cs_restart_write_linked_fields()

int cs_restart_write_linked_fields	(	cs_restart_t *	r,
		const char *	key,
		int	write_flag[]
	)

Write fields depending on others to checkpoint.

Parameters

[in,out]	r	associated restart file pointer
[in]	key	key for field association
[in,out]	write_flag	optional flag to track fields written, or NULL; set to sum of 2^time_id for fields written (size: n_fields)

Returns

number of fields written

cs_restart_write_variables()

void cs_restart_write_variables	(	cs_restart_t *	r,
		int	t_id_flag,
		int	write_flag[]
	)

Write variables to checkpoint.

Parameters

[in,out]	r	associated restart file pointer
[in]	t_id_flag	-1: all time values; 0: current values; > 0: previous values
[in,out]	write_flag	optional flag to track fields written, or NULL; set to sum of 2^time_id for fields written (size: n_fields)
