- intended for the following type of use:
auto oldHandler = fileHandler(fileOperation::NewUncollated());
... do something that only works with uncollated
// Restore previous (if any)
if (oldHandler)
{
fileHandler(std::move(oldHandler));
}
ENH: make fileOperation distributed(bool) mutable
- use is "static-like" and akin to Pstream::parRun(bool),
thus allow toggling of the switch without a const_cast

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;
