Class
    Foam::fixedInternalValueFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    This boundary condition provides a mechanism to set boundary (cell) values
    directly into a matrix, i.e. to set a constraint condition.  Default
    behaviour is to act as a zero gradient condition.
 
    \heading Patch usage
 
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            fixedInternalValue;
        value           uniform 0;              // place holder
    }
    \endverbatim
 
Note
    This is used as a base for conditions such as the turbulence \c epsilon
    wall function, which applies a near-wall constraint for high Reynolds
    number flows.
