Description🔗
The yPlus
function object computes the near wall \(y_1^+\) for turbulence
models.
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 yPlus
function object by using functions
sub-dictionary in
system/controlDict
file:
yPlus1
{
// Mandatory entries (unmodifiable)
type yPlus;
libs (fieldFunctionObjects);
// 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: yPlus | word | yes | - |
libs | Library name: fieldFunctionObjects | word | yes | - |
The inherited entries are elaborated in:
Example by using the postProcess
utility:
<solver> -postProcess -func yPlus
