Execuse me,

I wanted to employ the use-defined drag coefficient between two fluid phases when setting the fluid-fluid exchange coefficient using the Euler multiphase model. However, the help files did not explain what the return value should be. The interphase exchange coefficient Kpq? The drag function f? Or the drag coefficient CD?

Best wishes.
