Application

Group
grpPostProcessingUtilities
Description
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.
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 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;
}
\endverbatim
