- the uncollated version becomes quite difficult to process. Caveat: cannot use "collateTimes true" for non-static geometries

Description
|
|
Utility to perform noise analysis of pressure data.
|
|
|
|
The utility provides a light wrapper around the run-time selectable
|
|
noise model. Current options include:
|
|
- point, and
|
|
- surface noise.
|
|
|
|
\heading Example usage
|
|
|
|
\verbatim
|
|
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 file
|
|
inputFile "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
|
|
// Must be a power of 2, default = 2^16 (=65536)
|
|
N 4096;
|
|
|
|
// Write interval for FFT data, default = 1
|
|
fftWriteInterval 100;

|
}
