Hi

I'm using v2.1.0. When using the blended scheme for the divergence in the momentum equations, which schemes are actually blended?

Is it standard Central Differencing (CD) scheme of second order accurancy and a Upwind Scheme of second order, or is it CD and Upwind of first order?

I use the blended scheme by setting the following in fvSchemes:

divSchemes
{
default none;

div(phi,U) Gauss blended 0.9;

....

}

Is this correct?

Kind regards
Jan

blended blends with CD and first order Upwind

You can find this in:

You can also check out the other schemes you might need here.
