uniformMixed

Description

The uniformMixed is a mixed-type boundary condition that mix a uniform fixed value and a niform patch-normal gradient condition. The term "uniform" is a legacy name since the prescribed values were previously spatially uniform across that patch.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type                uniformMixed;

    // Optional entries
    uniformValue        <PatchFunction1<Type>>;
    uniformGradient     <PatchFunction1<Type>>;

    // Conditional entries

        // if both 'uniformValue' and 'uniformGradient' entries are set
        uniformValueFraction    <PatchFunction1<Type>>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: uniformMixed	word	yes	-
uniformValue	Uniform fixed values	PatchFunction1<Type>	no	-
uniformGradient	Uniform gradient values	PatchFunction1<Type>	no	-
uniformValueFraction	Fraction values	PatchFunction1<Type>	conditional	-
