Function Documentation

cs_get_glob_time_step()

cs_time_step_t* cs_get_glob_time_step

(

void

)

Provide read/write access to cs_glob_time_step.

Returns

pointer to global time step structure

cs_get_glob_time_step_options()

cs_time_step_options_t* cs_get_glob_time_step_options

(

void

)

Provide read/write access to cs_glob_time_step_options.

Returns

pointer to global time step options structure

cs_time_step_define_local()

void cs_time_step_define_local

(

int

is_local

)

Define whether time step is local in space or not.

Parameters

[in]

is_local

0 if time step is uniform in space, 1 if it is local

cs_time_step_define_nt_max()

void cs_time_step_define_nt_max

(

int

nt_max

)

Define maximum time step number.

Parameters

[in]

nt_max

maximum time step number (unlimited if negative)

cs_time_step_define_prev()

void cs_time_step_define_prev	(	int	nt_prev,
		double	t_prev
	)

Set time values from previous (usually restarted) calculations.

Parameters

[in]	nt_prev	previous time step number
[in]	t_prev	previous physical time

cs_time_step_define_t_max()

void cs_time_step_define_t_max

(

double

t_max

)

Define maximum time value.

Parameters

[in]

t_max

maximum time value (unlimited if negative)

cs_time_step_define_variable()

void cs_time_step_define_variable

(

int

is_variable

)

Define whether time step is variable or not.

Parameters

[in]

is_variable

0 if time step is variable in time, 1 if it is fixed

cs_time_step_increment()

void cs_time_step_increment

(

double

dt

)

Increment the global time step.

Parameters

[in]

dt

time step value to increment

cs_time_step_log_setup()

void cs_time_step_log_setup

(

void

)

Print the time stepping options to setup.log.

cs_time_step_redefine_cur()

void cs_time_step_redefine_cur	(	int	nt_cur,
		double	t_cur
	)

Redefine the current time values.

Remarks

Using cs_time_step_increment is preferred, but this function may be required for reverting to a previous time step.

Parameters

[in]	nt_cur	current time step number
[in]	t_cur	current physical time
