Hi all

I'm working on a simple simulation where two immiscible liquid flows in a pipe. I'm using VoF model with two phases (both liquid, immiscible, properties separately defined, surface tension force modelling enabled).

When I was trying to check some results, the volume fraction contours of both phases shows fine. However the contours or vectors of velocity can only choose the phase "mixture" instead of my two phases in the "phase" drop-down list. Why is this?

Many thanks

VOF model calculates only one velocity field, that of the mixture. So both phases share the same velocity.
