Courant number blended divergence scheme

Properties​

  • Blends two schemes based on the local face-based Courant number

Usage​

The scheme is specified using:

divSchemes
{
    default         none;
    div(phi,U)      Gauss CoBlended <co1> <scheme1> <co2> <scheme2>;
}

Where

  • Co < co1 : scheme1
  • Co > co2 : scheme2
  • co1 < Co < co2 : linear blend between <scheme1> and <scheme2>

Note: If a scheme with optional entries (such as the DEShybrid scheme) is used as <scheme1> within CoBlended, the user must provide all entries, both mandatory and optional. Failing to do so will result in a fatal error.
