Detailed Description

Evaluates and writes the following power fields.

+ tauUSf:           tauf & Uf
+ divTauU:          fvc::div(tauUSf)
+ divTauDotU:       fvc::div(tauf) & U
+ tauDDotGradU:     divTauU - divTauDotU

+ pUSf:            -pIf & Uf
+ divPU:            fvc::div(pUSf)
+ gradPU:          -fvc::grad(p) & U
+ pDivU:            divPU - gradPU

+ stressUSf:        tauUSf + pUSf
+ divStressU:       fvc::div(stressUSf)
+ divStressDotU:    fvc::div(stressf) & U
+ stressDDotGradU:  divStressU - divStressDotU

where:

+ p, U = cell centre pressure and velocity
+ pIf, Uf = face normal pressure force, and velocity, vectors
+ tauf = face shear force vectors [-transport.devTau()*mesh().magSf()]
+ stressf = tauf - pIf

The domain integral of the volume fields (all except '...Sf' fields) is also printed to a log file in the postProcessing directory. Domain integrals are scaled by a factor, which defaults to 1e9, to make them easier to process.

Usage

An example is given below of a function object specification in the system/functions file with a scaling factor of 1e6 for the domain integrals

power
{
    type        power;
    libs        ("libfieldFunctionObjects.so");
    executeControl  writeTime;
    writeControl    writeTime;
    log             true;
    factor          1e6;
}

Alternatively it can be specified using the standard 'power' function object configuration file as follows
