Properties🔗

• Second order
• Unbounded
• Attempts to limit the unboundedness of the linear scheme

Usage🔗

The scheme is specified using:

divSchemes
{
    default         none;
    div(phi,U)      Gauss filteredLinear2 <k> <l>;
}

Where the coefficients

• k: Scales the rate at which the correction is applied
  • 0 : linear
  • 1 : fully limited
• l: Maximum allowed overshoot/undershoot relative to the difference across the face.
  • 0 : no overshoot/undershoot
  • 1 : overshoot/undershoot equal to the difference across the face
