Hello,

I have carried out a multiphase simulation of polymer/air using VOF.

I'm interested in knowing the velocity of the interface between the polymer/air. How could I do it?

Thanks in advance

In fact the technical term is "melt front velocity"

Someone know how to know the melt front velocity of a 2-phases VOF simulation with ANSYS Fluent?

ghost82 will become famous soon enough
What about creating an isosurface=0.5 (this should be the polymer-air interface) and colour it by velocity?
