Class
    Foam::mappedPatchFieldBase
 
Description
    Functionality for sampling fields using mappedPatchBase. Every call to
    mappedField() returns a sampled field, optionally scaled to maintain an
    area-weighted average.
 
    Example usage:
 
    {
        fieldName           T;          // default is same as fvPatchField
        setAverage          false;
        average             1.0;        // only if setAverage=true
        interpolationScheme cellPoint;  // default is cell
    }
