Detailed Description

Calculates and write the shear-stress at wall patches as the volVectorField field 'wallShearStress'.

$Stress = R \dot n$

where

	=	stress tensor
	=	patch normal vector (into the domain)

The shear-stress symmetric tensor field is retrieved from the turbulence model. All wall patches are included by default; to restrict the calculation to certain patches, use the optional 'patches' entry.

Example of function object specification:

    wallShearStress1
    {
        type        wallShearStress;
        libs        ("libfieldFunctionObjects.so");
        ...
        patches     (".*Wall");
    }

Usage

Property	Description	Required	Default value
`type`	type name: wallShearStress	yes
`patches`	list of patches to process	no	all wall patches

Note: Writing field 'wallShearStress' is done by default, but it can be overridden by defining an empty objects list. For details see writeLocalObjects.
