Description🔗
The DESModelRegions
function object computes an indicator field for
detached eddy simulation (DES) turbulence calculations, where the values
the indicator mean:
0 = Reynolds-averaged Navier-Stokes (RAS) regions
1 = Large eddy simulation (LES) regions
The DESModelRegions
function object can only be executed for DES simulations.
Operands🔗
Operand | Type | Location |
---|---|---|
input | - | - |
output file | dat | $FOAM_CASE/postProcessing/<FO>/<time>/<file> |
output field | volScalarField | $FOAM_CASE/<time>/<outField> |
Usage🔗
Example of the DESModelRegions
function object
by using functions
sub-dictionary in system/controlDict
file:
DESModelRegions1
{
// Mandatory entries (unmodifiable)
type DESModelRegions;
libs (fieldFunctionObjects);
// Optional entries (runtime modifiable)
result DESField;
// Optional (inherited) entries
writePrecision 8;
writeToFile true;
useUserTime true;
region region0;
enabled true;
log true;
timeStart 0;
timeEnd 1000;
executeControl timeStep;
executeInterval 1;
writeControl timeStep;
writeInterval 1;
}
where the entries mean:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type | Type name: DESModelRegions | word | yes | - |
libs | Library name: fieldFunctionObjects | word | yes | - |
result | Name of DES indicator field | word | no | <FO> |
The inherited entries are elaborated in:
