CeedQFunction¶

int CeedQFunctionRegister(const char *name, const char *source, CeedInt vlength, CeedQFunctionUser f, int (*init)(Ceed, const char*, CeedQFunction))¶

Register a gallery QFunction.

Library Developer Functions

Return

An error code: 0 - success, otherwise - failure

Parameters

name: Name for this backend to respond to
source: Absolute path to source of QFunction, “\path\CEED_DIR\gallery\folder\file.h:function_name”
vlength: Vector length. Caller must ensure that number of quadrature points is a multiple of vlength.
f: Function pointer to evaluate action at quadrature points. See Public API for CeedQFunction.
init: Initialization function called by CeedQFunctionInit() when the QFunction is selected.

int CeedQFunctionFieldSet(CeedQFunctionField *f, const char *fieldname, CeedInt size, CeedEvalMode emode)¶

Set a CeedQFunction field, used by CeedQFunctionAddInput/Output.

Library Developer Functions

Return

An error code: 0 - success, otherwise - failure

Parameters

f: CeedQFunctionField
fieldname: Name of QFunction field
size: Size of QFunction field, (ncomp * dim) for CEED_EVAL_GRAD or (ncomp * 1) for CEED_EVAL_NONE, CEED_EVAL_INTERP, and CEED_EVAL_WEIGHT
emode: CEED_EVAL_NONE to use values directly, CEED_EVAL_INTERP to use interpolated values, CEED_EVAL_GRAD to use gradients, CEED_EVAL_WEIGHT to use quadrature weights.

int CeedQFunctionFieldView(CeedQFunctionField field, CeedInt fieldnumber, bool in, FILE *stream)¶

View a field of a CeedQFunction.

Utility Functions

Return

An error code: 0 - success, otherwise - failure

Parameters

[in] field: QFunction field to view
[in] fieldnumber: Number of field being viewed
[in] in: true for input field, false for output
[in] stream: Stream to view to, e.g., stdout

int CeedQFunctionSetFortranStatus(CeedQFunction qf, bool status)¶

Set flag to determine if Fortran interface is used.

Backend Developer Functions

Return

An error code: 0 - success, otherwise - failure

Parameters

qf: CeedQFunction
status: Boolean value to set as Fortran status
