Fluent/ CFX Phase dependent boundary condition VoF — Ansys Learning Forum

# Fluent/ CFX Phase dependent boundary condition VoF

Member Posts: 19

Hello to all,

I am very new to Ansys Fluent and would like to simulate the injection molding process though VoF.

However, one of the boundaries I must include is a dynamic wall/outlet, where:

no-slip boundary is assigned if,

Otherwise, a "traction-free" boundary is imposed

Is it possible to implement this into Fluent/ does it already have this implemented? If so, where can I find its documentation.

If not, to implement the traction free boundary:

Can I just set the velocity gradient to zero and impose a fixed value of 0 for the pressure?

Best Regards!
