Class
Foam::functionObjects::energySpectrum
Group
grpFieldFunctionObjects
Description
Calculates the energy spectrum for a structured IJK mesh
Usage
Example of function object specification:
\verbatim
energySpectrum1
{
type energySpectrum;
libs (fieldFunctionObjects);
...
log yes;
}
\endverbatim
Where the entries comprise:
\table
Property | Description | Required | Default value
type | type name: energySpectrum | yes |
log | write info to standard output | no | yes
\endtable
Output data is written to the file \<timeDir\>/energySpectrum.dat
