check_disk_space QQQQ

Here is the caller graph for this function:

rz_array_t* rz_new_3d_a	(	int	r0,
		int	z0,
		int	r1,
		int	z1,
		int	ntheta
	)

Creates a new 3D array structure.

Here is the call graph for this function:

Here is the caller graph for this function:

rz_array_t* rz_guest	(	rz_array_t *	host,
		int	r0,
		int	z0,
		int	r1,
		int	z1
	)

Creates guest array: This is an array that contains part of another one.

We use the memory of the original array and do not allocate new memory.

Here is the caller graph for this function:

void rz_set_zero ( rz_array_t * array )

Sets the data of an array to zero.

Definition at line 145 of file rz_array.c.

Here is the caller graph for this function:

void rz_set_periodic ( rz_array_t * array )

Sets periodic boundary conditions for theta in an array.

Definition at line 153 of file rz_array.c.

Here is the call graph for this function:

Here is the caller graph for this function:

void rz_copy_bnd	(	rz_array_t *	from,
		rz_array_t *	to,
		int	sign,
		REAL *	start_from,
		REAL *	start_to,
		int	dim0,
		int	inout_from,
		int	inout_to,
		int	dim1,
		int	dim1_0,
		int	dim1_1,
		int	dim2,
		int	dim2_0,
		int	dim2_1
	)

Sets boundaries for one array reading data from other array (but both can be the same: see rz_set_bnd).

Starting at *start_xxx, it sweeps a 2-dimensional subspace of the grid in dimensions dim1 and dim2 (and perpendicular to dim0). There it sets the boudary conditions.

The value of from is multiplied by sign. Thus, if the boundary is itself, is -1 for homogeneous dirichlet and 1 for homogeneous Neumann (though you should better use BND_CND_HNEUMANN and BND_CND_HDIRICHLET)

inout is -1 if we look/set the values on smaller values of dim0 1 if we look at larger values. (though it is better to use BND_INWARD=-1 and BND_OUTWARD=1).

Note: it is better to call this function before rz_set_periodic.

Definition at line 196 of file rz_array.c.

Here is the caller graph for this function:

void rz_set_bnd	(	rz_array_t *	array,
		int	sign,
		REAL *	astart,
		int	dim0,
		int	inout,
		int	dim1,
		int	dim1_0,
		int	dim1_1,
		int	dim2,
		int	dim2_0,
		int	dim2_1
	)

Sets boundary conditions (Neumann/Dirichlet) reading from the array itself.

For example, to set Neumann conditions at r = 0 (dim0 = R_INDX), we call it as

rz_set_bnd (array, 1, RZTP (array, 0, 0, 0), R_INDX, 1, Z_INDX, z0, z1, THETA_INDX, 0, ntheta);

Here is the caller graph for this function:

void rz_dump	(	rz_array_t *	rz_array,
		const char *	fname,

		int	z0,
		int	r1,
		int	z1
	)

Reads or writes a rz_array, depending on the string mode, "r" for reading, "w" for writing.

Note however that we must already have the dimensions of the array in it.

Variable Documentation

long int used_disk_space = 0

This is the total disk space used so far for the array dumps. It is used to limit the disk space used by a simulation and thus avoid that one simulation gets crazy and stops other simulations that are sharing the same disk space.
