函数说明

flu_var_init()

static double * flu_var_init ( const char *  add, FILE *  fp  )

static

This function count out and read in 2-D data file with (line*column) data and initialize pointer to these data.

The value of (line*column) is stored in config[3]; the value (line) number is stored in config[13]; the value (column) number is stored in config[14];

参数

[in]	add	Adress of the initial data file.
[in]	fp	Pointer to the input data file.

返回

Pointer to the position of a block of memory consisting (line*column) variables of type double.

initialize_2D()

struct flu_var initialize_2D	(	const char *	name,
		int *	N,
		int *	N_plot,
		double *	time_plot[]
	)

This function reads the 2-D initial data file of density/velocity/pressure.

The function initialize the extern pointer FV0.RHO/U/V/P pointing to the position of a block of memory consisting (line*column) variables* of type double. These (line*column) variables are the initial value.

参数

[in]	name	Name of the test example.
[in]	N	Pointer to the number of 2-D data dimension storing fluid variables in memory.
[out]	N_plot	Pointer to the number of time steps for plotting.
[out]	time_plot	Pointer to the array of the plotting time recording.

返回

FV0: Structure of initial fluid variable data array pointer.

注解

This function contains the function procedures 'time_plot_read()' and 'configurate()'.
