Gauss DEShybrid
 
Hi,

i have a question regarding the scheme -->

How do i define the values for the references? Are there any rule of thumbs for that?

divSchemes
{
div(phi,U) Gauss DEShybrid
linear // scheme 1
linearUpwind grad(U) // scheme 2
delta
0.65 // DES coefficient, typically = 0.65
30 // Reference velocity scale
2 // Reference length scale

0 // Minimum sigma limit (0-1)
1; // Maximum sigma limit (0-1)
}

Yuanchuan,

still no idea yet. Happy about every help.
Does anyone have something in writing for that?
