Function Documentation

cs_restart_finalize_fields_read_status()

void cs_restart_finalize_fields_read_status

(

void

)

Finalize fields read status array.

cs_restart_get_field_read_status()

int cs_restart_get_field_read_status

(

const int

f_id

)

Get checkpoint read status for a field based on its id.

Parameters

[in]

f_id

field id

Returns

0 if field read action failed, 1 otherwise

cs_restart_initialize_fields_read_status()

void cs_restart_initialize_fields_read_status

(

void

)

Initialize fields read status array.

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 nullptr; set to sum of 2^time_id for fields read, -1 for fields failed to read (size: n_fields)

cs_restart_read_notebook_variables()

void cs_restart_read_notebook_variables

(

cs_restart_t *

r

)

Read notebook parameters from main checkpoint.

Parameters

[in,out]

r

associated restart file pointer

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]	t_id_flag	-1: all time values; 0: current values; > 0: previous values
[in,out]	read_flag	optional flag to track fields read, or nullptr; set to sum of 2^time_id for fields read (size: n_fields)

cs_restart_set_auxiliary_field_options()

void cs_restart_set_auxiliary_field_options

(

)

Set restart file values for fields when those values cannot be determined at field definition time.

This is needed when the need for restart data depends on various combinations of settings.

Write boundary condition coefficients for all fields to checkpoint.

Parameters

[in,out]
