Public Macros

StencilElementMacro(name, value, minDim, offset, rowFldIndx, colFldIndx)

Insert a constant-value matrices StencilElement.

Parameters

• name – The name to give the stencil element.

• value – The value of the stencil element.

• minDim – The minimum dimensionality to apply this stencil element.

• offset – The offset (in index space) of the column cell from the row cel.

• rowFldIndx – The index in the matrices for the row. This corresponds to the writefield for multiply, to the readfield for solve.

• colFldIndx – The index in the matrices for the column. This corresponds to the readfield for multiply, to the writefield for solve.

STFuncStencilElementMacro(name, value, minDim, cellOffset, funcOffset, rowFldIndx, colFldIndx)

Insert a function-value matrices StencilElement.

Parameters

• name – The name to give the stencil element.

• value – The value of the stencil element.

• minDim – The minimum dimensionality to apply this stencil element.

• cellOffset – The offset (in index space) of the column cell from the row cel.

• funcOffset – The offset (in real space, as a multiple of the grid spacing) of the function evaluation point from the row cell.

• rowFldIndx – The index in the matrices for the row. This corresponds to the writefield for multiply, to the readfield for solve.

• colFldIndx – The index in the matrices for the column. This corresponds to the readfield for multiply, to the writefield for solve.

CoordProdSTFuncStencilElementMacro(name, value, minDim, cellOffset, funcOffset, gridDir, gridOffset, rowFldIndx, colFldIndx)

Insert a function-value matrices StencilElement in coordProd grid.

Parameters

• name – The name to give the stencil element.

• value – The value of the stencil element.

• minDim – The minimum dimensionality to apply this stencil element.

• cellOffset – The offset (in index space) of the column cell from the row cel.

• funcOffset – The offset (in real space, as a multiple of the grid spacing) of the function evaluation point from the row cell.

• gridDir – The direction in which differencing is being done for the stencil. Determines which grid spacing and face area to use.

• gridOffset – The offset (in index space) from the row cell at which the grid spacing and face area are taken.

• rowFldIndx – The index in the matrices for the row. This corresponds to the writefield for multiply, to the readfield for solve.

• colFldIndx – The index in the matrices for the column. This corresponds to the readfield for multiply, to the writefield for solve.
