Detailed Description

Function Documentation

F5AMRclose()

F5_API void F5AMRclose

(

AMRInfo *

)

Releases the data structure that had been allocated by the F5AMRopen() call.

References F5_API.

F5AMRopen()

F5_API AMRInfo * F5AMRopen	(	hid_t	fileID,
		const int	rank,
		double	rootOrigin[3],
		double	rootDelta[3],
		const char *	description )

Adds AMR data to an HDF5 file.

Parameters

fileID	An HDF5 id as returned by the H5Fopen() or H5Fcreate() calls.
rank	Dimensionality of the data.
rootOrigin	minimal coordinate of root level bounding box
rootDelta	cell-size on root level
description	A short description about the data set. It should be short and contain no special characters or spaces. The same rules as for file names apply here. Ie. special characters and long names are possible, but it is better to avoid them.

Returns

A pointer to an AMRInfo structure, which allows to set further information for each AMR level. The per-level information must be set in the structure. The result must be released by the F5AMRclose() function.

F5AMRwrite_block()

F5_API herr_t F5AMRwrite_block	(	AMRInfo *	AI,
		const int	timestep,
		const double	physTime,
		const char *	fieldname,
		const int	level,
		int	dimension,
		const int *	location,
		const int *	size,
		hid_t	fieldtype,
		const void *	dataPtr,
		int	Centering,
		const char *	blockname,
		const char *	coordinate_system,
		hid_t	property_id )

Writes out a single AMR data box. The data layout of non-scalar field is an array of struct.

Parameters

AI	Some AMRInfo data structure which was created by an F5AMROpen() call.
timestep	counted in steps on the highest level of resolution
physTime	associated physical time of this timestep
level	refinement level this box belongs to
dimension	The dimensionality of the data.
location	Origin of this grid in coordinates given by the cells on this level, must be consistent with the dimension parameter.
size	Number of elements of data array in each dimension, must be consistent with the dimension parameter.
dataPtr	Pointer to data array, the number of elements must be consistent with the size parameter.
fieldname	Some name of the field (density, pressure, ...)
fieldtype	HDF5 data type identifier. The caller is responsible for creating a corect HDF5 description of the provided data.
Centering	bit array of flags to specify where relative to a uniform cell the data reside.
blockname	An (optional) identifier for each block.
property_id	An HDF5 dataset property (may specify data chunking, compression etc.). May be F5P_DEFAULT.

F5AMRwrite_block_v()

F5_API herr_t F5AMRwrite_block_v	(	AMRInfo *	AI,
		const int	timestep,
		const double	physTime,
		const char *	fieldname,
		const int	level,
		int	dimension,
		const int *	location,
		const int *	size,
		hid_t	fieldtype,
		const void **	dataPtr,
		int	Centering,
		const char *	blockname,
		const char *	coordinate_system,
		hid_t	property_id )

Writes out a single AMR data box. The data layout of non-scalar field is a struct of arrays, ie. the data fields of each component of eg. some vector field resides in different scalar arrays.

Parameters

AI	Some AMRInfo data structure which was created by an F5AMROpen() call.
timestep	counted in steps on the highest level of resolution
physTime	associated physical time of this timestep
level	refinement level this box belongs to
dimension	The dimensionality of the data.
location	Origin of this grid in coordinates given by the cells on this level, must be consistent with the dimension parameter.
size	Number of elements of data array in each dimension, must be consistent with the dimension parameter.
dataPtr	Array of pointer to data arrays, the number of elements must be consistent with the size parameter.
fieldname	Some name of the field (density, pressure, ...)
fieldtype	HDF5 data type identifier. The caller is responsible for creating a corect HDF5 description of the provided data.
Centering	bit array of flags to specify where relative to a uniform cell the data reside.
blockname	An (optional) identifier for each block.
property_id	An HDF5 dataset property (may specify data chunking, compression etc.). May be F5P_DEFAULT.
