Mixed

Properties

  • Robin condition
  • a linear blend of fixed value and gradient conditions
  • blending specified using a value fraction
  • not usually applied directly, but used in derived types, e.g. the inletOutlet condition
  • explicit and implicit contributions

Face values are evaluated according to:

\[ \phi_f = w \phi_{ref} + \left(1-w\right)\left(\phi_c + \Delta \grad{\phi}_{ref} \right) \]

where

\( \phi_f \) = face value
\( \phi_c \) = cell value
\( \phi_{ref} \) = reference value
\( \Delta \) = face-to-cell distance
\( w \) = value fraction

Usage

<patchName>
{
    type            mixed;
    refValue        <field value>;
    refGradient     <field value>;
    valueFraction   <field value>;
}
