fixedMean

Description

The fixedMean is a general boundary condition to extrapolate a field to the patch using the near-cell values and adjusts the distribution to match the specified, optionally time-varying, mean value.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            fixedMean;
    meanValue       <Function1<Type>>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: fixedMean	word	yes	-
meanValue	Mean value that the field is adjusted to maintain	Function1<Type>	yes	-
