Detailed Description

template<class Type>
class Foam::CoBlended< Type >

Two-scheme Courant number based blending differencing scheme.

Similar to localBlended but uses a blending factor computed from the face-based Courant number and the lower and upper Courant number limits supplied:

\[ weight = 1 - max(min((Co - Co1)/(Co2 - Co1), 1), 0) \]

where

$ Co1 $ = Courant number below which scheme1 is used
$ Co2 $ = Courant number above which scheme2 is used

The weight applies to the first scheme and 1-weight to the second scheme.

Example of the CoBlended scheme specification using LUST for Courant numbers less than 1 and linearUpwind for Courant numbers greater than 10:

    divSchemes
    {
        .
        .
        div(phi,U)      Gauss CoBlended 1 LUST grad(U) 10 linearUpwind grad(U);
        .
        .
    }
