Detailed Description

Low-level corner-point processing routines and supporting data structures.

User code should typically employ higher-level routines such as create_grid_cornerpoint() in order to construct fully formed UnstructuredGrid data structures from a corner-point specification. Incidentally, the routines provided by this module are used to implement function create_grid_cornerpoint().

Enumeration Type Documentation

enum face_tag

Connection taxonomy.

Enumerator
LEFT	Connection topologically parallel to J-K plane.
BACK	Connection topologically parallel to I-K plane.
TOP	Connection topologically parallel to I-J plane.

Function Documentation

void free_processed_grid

(

struct processed_grid *

g

)

Release memory resources acquired in previous grid processing using function process_grdecl().

Note: This function releases the resources associated to the individual fields of the processed_grid, but does not free() the structure itself.

Parameters

[in,out]

g

Prototypical grid representation obtained in an earlier call to function process_grdecl().

void process_grdecl	(	const struct grdecl *	g,
		double	tol,
		struct processed_grid *	out
	)

Construct a prototypical grid representation from a corner-point specification.

Pinched cells will be removed irrespective of any explicit "active" map in the geological model input specification. On input, the result structure "out" must point to a valid management structure. In other words, the result structure must point to a region of memory that is typically backed by automatic or allocated (dynamic) storage duration.

Parameters

[in]	g	Corner-point specification. If "actnum" is NULL, then the specification is interpreted as if all cells are initially active.
[in]	tol	Absolute tolerance of node-coincidence.
[in,out]	out	Minimal grid representation featuring face-to-cell neighbourship definition, vertex geometry, face's constituent vertices, and local-to-global cell mapping.
