Detailed Description

Driver for patch expressions.

In addition to the standard mathematical functions, operations and logical and relational operations, the patch expressions support the following driver-specific functions:

Functions

Function	Description	Number of arguments
`pos`	The face centres	0
`pts`	The face points	0
`area`	The face area magnitudes	0
`weightAverage`	Area weighted average	1
`weightSum`	Area weighted sum	1
`face`	The face areaNormal vectors	0
`point`	A point-field point value	1
`faceToPoint`	Interpolate face values onto points	1
`pointToFace`	Interpolate point values onto faces	1
`rand`	Random field	0/1
`snGrad`	Surface normal field	0
`internalField`	Internal field next to patch	0
`neighbourField`	patch field on opposite side of coupled patch	0

Note: Use namespace debug switch patchExpr for scanner (2), parser (4) or dictionary controls as per Foam::expressions::exprDriver.
