32 Appendix A: Master List of Constants

32.1 ESMC_CALKIND

This flag is documented in section 25.2.1.

32.2 ESMC_COORDSYS

This flag is documented in section 19.2.1.


32.3 ESMC_DECOMP

DESCRIPTION:
Indicates how DistGrid elements are decomposed over DEs.

The type of this flag is:

type(ESMC_Decomp_Flag)

The valid values are:

ESMC_DECOMP_BALANCED
Decompose elements as balanced as possible across DEs. The maximum difference in number of elements per DE is 1, with the extra elements on the lower DEs.
ESMC_DECOMP_CYCLIC
Decompose elements cyclically across DEs.
ESMC_DECOMP_RESTFIRST
Divide elements over DEs. Assign the rest of this division to the first DE.
ESMC_DECOMP_RESTLAST
Divide elements over DEs. Assign the rest of this division to the last DE.

type(ESMC_ExtrapMethod_Flag)

DESCRIPTION:
Specify which extrapolation method to use on unmapped destination points after regridding.

The type of this flag is:

type(ESMC_ExtrapMethod_Flag)

The valid values are:

ESMC_EXTRAPMETHOD_NONE
Indicates that no extrapolation should be done.
ESMC_EXTRAPMETHOD_NEAREST_STOD
Inverse distance weighted average. Here the value of a destination point is the weighted average of the closest N source points. The weight is the reciprocal of the distance of the source point from the destination point raised to a power P. All the weights contributing to one destination point are normalized so that they sum to 1.0. The user can choose N and P when using this method, but defaults are also provided.
ESMC_EXTRAPMETHOD_NEAREST_IDAVG
Nearest source to destination. Here each destination point is mapped to the closest source point. A given source point may go to multiple destination points, but no destination point will receive input from more than one source point.

32.4 ESMC_FILEFORMAT

This flag is documented in section 19.2.6.

32.5 ESMC_GRIDITEM

This flag is documented in section 19.2.2.

32.6 ESMC_GRIDSTATUS

This flag is documented in section 19.2.3.


32.7 ESMC_INDEX

DESCRIPTION:
Indicates whether index is local (per DE) or global (per object).

The type of this flag is:

type(ESMC_IndexFlag)

The valid values are:

ESMC_INDEX_DELOCAL
Indicates that DE-local index space starts at lower bound 1 for each DE.
ESMC_INDEX_GLOBAL
Indicates that global indices are used. This means that DE-local index space starts at the global lower bound for each DE.
ESMC_INDEX_USER
Indicates that the DE-local index bounds are explicitly set by the user.


32.8 ESMC_LINETYPE

DESCRIPTION:
This argument allows the user to select the path of the line which connects two points on the surface of a sphere. This in turn controls the path along which distances are calculated and the shape of the edges that make up a cell.

The type of this flag is:

type(ESMC_LineType_Flag)

The valid values are:

ESMC_LINETYPE_CART
Cartesian line. When this option is specified distances are calculated in a straight line through the 3D Cartesian space in which the sphere is embedded. Cells are approximated by 3D planes bounded by 3D Cartesian lines between their corner vertices. When calculating regrid weights, this line type is currently the default for the following regrid methods: ESMC_REGRIDMETHOD_BILINEAR, ESMC_REGRIDMETHOD_PATCH, ESMC_REGRIDMETHOD_NEAREST_STOD, and ESMC_REGRIDMETHOD_NEAREST_DTOS.
ESMC_LINETYPE_GREAT_CIRCLE
Great circle line. When this option is specified distances are calculated along a great circle path (the shortest distance between two points on a sphere surface). Cells are bounded by great circle paths between their corner vertices. When calculating regrid weights, this line type is currently the default for the following regrid method: ESMC_REGRIDMETHOD_CONSERVE.

32.9 ESMC_LOGKIND

This flag is documented in section 30.2.1.

32.10 ESMC_LOGMSG

This flag is documented in section 30.2.2.

32.11 ESMC_MESHELEMTYPE

This flag is documented in section 20.2.1.


32.12 ESMF_METHOD

DESCRIPTION:
Specify standard ESMF Component method.

The type of this flag is:

type(ESMF_Method_Flag)

The valid values are:

ESMF_METHOD_FINALIZE
Finalize method.
ESMF_METHOD_INITIALIZE
Initialize method.
ESMF_METHOD_READRESTART
ReadRestart method.
ESMF_METHOD_RUN
Run method.
ESMF_METHOD_WRITERESTART
WriteRestart method.

32.13 ESMC_POLEKIND

This flag is documented in section 19.2.4.


32.14 ESMC_REDUCE

DESCRIPTION:
Indicates reduce operation.

The type of this flag is:

type(ESMC_Reduce_Flag)

The valid values are:

ESMC_REDUCE_SUM
Use arithmetic sum to add all data elements.
ESMC_REDUCE_MIN
Determine the minimum of all data elements.
ESMC_REDUCE_MAX
Determine the maximum of all data elements.


32.15 ESMC_REGION

DESCRIPTION:
Specifies various regions in the data layout of an Array or Field object.

The type of this flag is:

type(ESMC_Region_Flag)

The valid values are:

ESMC_REGION_TOTAL
Total allocated memory.
ESMC_REGION_SELECT
Region of operation-specific elements.
ESMC_REGION_EMPTY
The empty region contains no elements.

32.16 ESMC_REGRIDMETHOD

This flag is documented in section 16.2.1.

32.17 ESMC_STAGGERLOC

This flag is documented in section 19.2.5.


32.18 ESMC_TYPEKIND

DESCRIPTION:
Named constants used to indicate type and kind combinations supported by the overloaded ESMC interfaces. The corresponding Fortran kind-parameter constants are described in the ESMF_TYPEKIND section of Appendices of the ESMF Fortran reference manual.

The type of these named constants is:

type(ESMC_TypeKind_Flag)

The named constants are:

ESMC_TYPEKIND_I1
Indicates 1 byte integer.
(Only available if ESMF was built with ESMF_NO_INTEGER_1_BYTE = FALSE. This is not the default.)
ESMC_TYPEKIND_I2
Indicates 2 byte integer.
(Only available if ESMF was built with ESMF_NO_INTEGER_2_BYTE = FALSE. This is not the default.)
ESMC_TYPEKIND_I4
Indicates 4 byte integer.
ESMC_TYPEKIND_I8
Indicates 8 byte integer.
ESMC_TYPEKIND_R4
Indicates 4 byte real.
ESMC_TYPEKIND_R8
Indicates 8 byte real.


32.19 ESMC_UNMAPPEDACTION

DESCRIPTION:
Indicates what action to take with respect to unmapped destination points and the entries of the sparse matrix that correspond to these points.

The type of this flag is:

type(ESMC_UnmappedAction_Flag)

The valid values are:

ESMC_UNMAPPEDACTION_ERROR
An error is issued when there exist destination points in a regridding operation that are not mapped by corresponding source points.
ESMC_UNMAPPEDACTION_IGNORE
Destination points which do not have corresponding source points are ignored and zeros are used for the entries of the sparse matrix that is generated.
