• Robin condition
  • a linear blend of fixedValue 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: \(\phi_f = w \phi_{\ref} + \left(1-w\right)\left(\phi_c + \Delta \grad{\phi}_{\ref} \right)\)

face value
cell value
reference value
face-to-cell distance

    type            mixed;
    refValue        <field value>;
    refGradient     <field value>;
    valueFraction   <field value>;
