fixedblended有人用过吗

不知道怎么声明啊，试了好几种排列组合，结果都不行。google也没有啥相关记录
那个系数该怎么整

Description
    Two-scheme fixed-blending differencing scheme.
    Similar to localBlended but uses a single (global) constant blending
    factor. The factor applies to the first scheme and 1-factor to the
    second scheme.
Note
    Although a blending factor of 0 and 1 is permitted, it is more efficient
    just to use the underlying scheme directly.

自己回答吧，
这个跟coblended还不一样，coblended的blendingfactor 得另外定义一个volScalarField。
但是fixedblended就加个系数就行了。
