Detailed Description

template<class Type>
class Foam::fixedGradientFvPatchField< Type >

This boundary condition supplies a fixed gradient condition, such that the patch values are calculated using:

\[ x_p = x_c + \frac{\nabla(x)}{\Delta} \]

where

\( x_p \)	=	patch values
\( x_c \)	=	internal field values
\( \nabla(x)\)	=	gradient (user-specified)
\( \Delta \)	=	inverse distance from patch face centre to cell centre

Usage

Property	Description	Required	Default value
`gradient`	gradient	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            fixedGradient;
        gradient        uniform 0;
    }
