Class
    Foam::noiseModels::pointNoise
 
Description
    Perform noise analysis on point-based pressure data.
 
    Input data is read from a dictionary, e.g.
 
    \verbatim
    // Pressure reference
    pRef            0;
 
    // Number of samples in sampling window, default = 2^16 (=65536)
    N               4096;
 
    // Lower frequency bounds
    fl              25;
 
    // Upper frequency bounds
    fu              25;
 
    // Start time
    startTime       0;
 
    windowModel     <modelType>
    <modelType>Coeffs
    {
        ...
    }
 
    // Pressure data supplied in CSV file format
    file            "pressureData";
    //files           ("pressureData1" "pressureData2");
    nHeaderLine     1;
    refColumn       0;
    componentColumns (1);
    separator       " ";
    mergeSeparators yes;
 
    \endverbatim
