Lagrange Particle Velocity

Thomas3D · May 5, 2009, 02:28

Hello everybody,

I have a question regarding Lagrange Particle Tracking.

Let's call the dispersed lagrange Phase "Water"

Does anybody know the difference between "Water.Averaged Velocity" and "Water.Velocity"?

In my results they are different, even in area's where water is present. As Water.velocity is uneven zero in area's without water beeing present, I assume that Water.Averaged Velocity is the way to go, right?

Does anybody know, why I can not export "Water.Mass Flow density" along a line?

Thanks for your time in advance,

Thomas3D

Regarding the massflow-averaging: there is no mass flow through a line-segment, hence you cannot calculate a massflow-average on a line.
