24 Class
25  Foam::fixedBlended
26 
27 Description
28  Two-scheme fixed-blending interpolation scheme.
29 
30  Similar to localBlended but uses a single (global) constant blending
31  factor. The factor applies to the first scheme and 1-factor to the
32  second scheme.
33 
34  Note:
35  Although a blending factor of 0 and 1 is permitted, it is more efficient
36  just to use the underlying scheme directly.
