Detailed Description

template<class Type>
class Foam::cellCoBlended< Type >

Two-scheme cell-based Courant number based blending differencing scheme.

This scheme is equivalent to the CoBlended scheme except that the Courant number is evaluated for cells using the same approach as use in the finite-volume solvers and then interpolated to the faces rather than being estimated directly at the faces based on the flux. This is a more consistent method for evaluating the Courant number but suffers from the need to interpolate which introduces a degree of freedom. However, the interpolation scheme for "Co" is run-time selected and may be specified in "interpolationSchemes" and "localMax" might be most appropriate.

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

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

interpolationSchemes
{
    .
    .
    interpolate(Co) localMax;
    .
    .
}
