4.9.2. API functions
[4.9. Grids]

The following function is used to define the type of grid. Gridtype is one of the following constants:

GRID_TYPE_CARTESIAN

GRID_TYPE_CURVILINEAR

GRID_TYPE_CARTESIAN_EXTRUDED

GRID_TYPE_CURVILINEAR_EXTRUDED.

C/C++

int xfSetGridType(xid GroupId, int GridType);

FORTRAN

SUBROUTINE XF_SET_GRID_TYPE (GroupId, GridType, Error)
INTEGER(XID), INTENT(IN) :: GroupId
INTEGER, INTENT(IN) :: GridType
INTEGER, INTENT(OUT)     :: Error

The following function is used only for extruded grids to define the type of extrusion taking place. Extrudetype must be one of the following constants:

EXTRUDE_SIGMA

EXTRUDE_CARTESIAN

EXTRUDE_CURV_AT_CORNERS

EXTRUDE_CURV_AT_CELLS

C/C++

int xfSetExtrusionType(xid GroupId, int ExtrudeType);

FORTRAN

SUBROUTINE XF_SET_EXTRUSION_TYPE(GroupId, ExtrudeType, Error)
INTEGER(XID), INTENT(IN) :: GroupId
INTEGER, INTENT(IN) :: ExtrudeType
INTEGER, INTENT(OUT)     :: Error

These functions are used to set attributes for a grid. The number of dimensions must be 2 or 3. Orientation must be one of the following constants ORIENTATION_RIGHT_HAND, ORIENTATION_LEFT_HAND. The computational origin is a number between 1 and 4 for 2D grids and between 1 and 8 for 3D grids. The number corresponds to the corner of the grid that will be the origin. The figures in the table below show the corresponding values. The u direction must be 1, 2, 3, -1, -2, or -3. This corresponds to the grid direction as labeled in the table. Negative direction values indicate the origin is at the other side of the grid. (For more information on the grid computational origin, see Appendix Grid).

Two Dimensional

Grid direction 1 - location 1 to location 2
Grid direction 2 - location 1 to location 4

Three Dimensional

Grid direction 1 - location 1 to location 2
Grid direction 2 - location 1 to location 4
Grid direction 3 - location 1 to location 5
