Detailed Description

Perform noise analysis of pressure data.

Original source file noise.C

The utility provides a light wrapper around the run-time selectable noise model. Current options include:

• point, and
• surface noise.

Usage

noiseModel      surfaceNoise; // pointNoise

surfaceNoiseCoeffs
{
    windowModel     Hanning;

    HanningCoeffs
    {
        // Window overlap percentage
        overlapPercent  50;
        symmetric       yes;
        extended        yes;

        // Optional number of windows, default = all available
        nWindow         5;
    }


    // Input files list
    files       ("postProcessing/faceSource1/surface/patch/patch.case";)

    // Surface reader
    reader      ensight;

    // Surface writer
    writer      ensight;

    // Collate times for ensight output
    // - ensures geometry is only written once
    writeOptions
    {
        ensight
        {
            collateTimes true;
        }
    }

    // Number of samples in sampling window, default = 2^16 (=65536)
    N               4096;

    // Write interval for FFT data, default = 1
    fftWriteInterval 100;
}
