Enums

The TecIO library often uses integers with special meanings (zone types, data types, data locations). The same values are used both for writing (tec*142 functions) and for SZL reading and writing (tec_* functions). The classes below provide a more readable format of these values. Where available, the equivalent keywords used in Tecplot ASCII files are set as the class property, returning the corresponding int value.

FileFormat	Binary data format selector.
FileType	Tecplot file type.
ZoneType	Tecplot zone type.
DataType	On-disk storage type for variable data.
ValueLocation	Data value location within a cell.
FaceNeighborMode	Boundary face-sharing mode between zones.
FeCellShape	Unstructured cell shape category.
DataPacking	Zone data packing order for ASCII (.dat) files.
VarStatus	Variable active/passive flag.
Boolean	Boolean flag for C function arguments.

class tecio.libtecio.FileType

Bases: Enum

Tecplot file type.

Attribute	Value	Description
FULL	0	Contains both grid and solution data.
GRID	1	Grid coordinates only.
SOLUTION	2	Solution variables only.

class tecio.libtecio.ZoneType

Bases: Enum

Tecplot zone type.

Attribute	Value	Description
ORDERED	0	Structured IJK grid.
FELINESEG	1	Finite-element line segments.
FETRIANGLE	2	Finite-element triangles.
FEQUADRILATERAL	3	Finite-element quadrilaterals.
FETETRAHEDRON	4	Finite-element tetrahedra.
FEBRICK	5	Finite-element hexahedra.
FEPOLYGON	6	Finite-element polygons (face-based).
FEPOLYHEDRON	7	Finite-element polyhedra (face-based).
FEMIXED	8	Mixed finite-element types.

class tecio.libtecio.DataType

Bases: Enum

On-disk storage type for variable data.

Attribute	Value	Description
FLOAT	1	32-bit IEEE floating point.
DOUBLE	2	64-bit IEEE floating point.
INT32	3	32-bit signed integer.
INT16	4	16-bit signed integer.
BYTE	5	8-bit unsigned integer.

class tecio.libtecio.ValueLocation

Bases: Enum

Data value location within a cell.

Attribute	Value	Description
CELL_CENTERED	0	Values stored at cell centres.
NODAL	1	Values stored at grid nodes.

class tecio.libtecio.FaceNeighborMode

Bases: Enum

Boundary face-sharing mode between zones.

Attribute	Value	Description
LOCAL_ONE_TO_ONE	0	Each face has at most one local neighbor.
LOCAL_ONE_TO_MANY	1	Each face may have multiple local neighbors (hanging nodes).
GLOBAL_ONE_TO_ONE	2	Each face has at most one neighbor in any zone.
GLOBAL_ONE_TO_MANY	3	Each face may have multiple neighbors in any zone (hanging nodes).

class tecio.libtecio.FeCellShape

Bases: Enum

Unstructured cell shape category.

Attribute	Value	Description
BAR	0	2D two-node element.
TRIANGLE	1	2D three-node element.
QUADRILATERAL	2	2D four-node element.
TETRAHEDRON	3	3D four-node element.
HEXAHEDRON	4	3D six-node element.
PYRAMID	5	3D five-node element.
PRISM	6	3D eight-node element.

class tecio.libtecio.DataPacking

Bases: Enum

Zone data packing order for ASCII (.dat) files.

Controls whether data is laid out variable-by-variable or point-by-point in the ASCII file. The DATAPACKING keyword in a zone header takes one of these two values.

Attribute	Value	Description
POINT	0	One row per node/cell containing all variable values.
BLOCK	1	One contiguous block per variable containing all node/cell values. Tecplot default; faster for variable-at-a-time access patterns.

class tecio.libtecio.VarStatus

Bases: Enum

Variable active/passive flag.

Attribute	Value	Description
ACTIVE	0	Variable has data in this zone.
PASSIVE	1	Variable has no data in this zone.

class tecio.libtecio.Boolean

Bases: Enum

Boolean flag for C function arguments.

Attribute	Value	Description
FALSE	0	Logical false.
TRUE	1	Logical true.
