$η_{1}$ $η_{1}$		$η_{2}$ $η_{2}$		$η_{3}$ $η_{3}$

Definitions

Field	Contents	SI Unit Example
$η_{1}$ $η_{1}$	Upwind coefficient on ALE momentum transport Default = 1.0 (Real)
$η_{2}$ $η_{2}$	Upwind coefficient on other ALE transports (mass, energy) Default = 1.0 (Real)
$η_{3}$ $η_{3}$	Upwind coefficient for wet area Default = 1.0 (Real)

Comments

This option can be used for ALE or Eulerian cases (momentum upwind formulation can be reset by using /UPWM options during restart: refer to the Engine Input).
$η_{3}$ $η_{3}$ is a coefficient for multi-phase law. $η_{3}$ $η_{3}$ is only available for /MAT/LAW51 (MULTIMAT).
