Class
    Foam::scaledFixedValueFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    This condition applies a scalar multiplier to the value of another
    boundary condition.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        scale        | Time varying scale      | yes         |
        refValue     | patchField providing the raw patch value | yes |
    \endtable
 
    Example of the boundary condition specification to scale a reference
    velocity of (15 0 0)  supplied as a fixedValue by a table of values
    that ramps the scale from 0 to 1 over 1 second:
    \verbatim
    <patchName>
    {
        type            scaledFixedValue;
 
        scale table
        (
            (    0   0)
            (  1.0 1.0)
            (100.0 1.0)
        );
 
        refValue
        {
            type            fixedValue;
            value           uniform (15 0 0);
        }
    }
    \endverbatim
