The discussion clarifies three key terms in Polyflow: "plane of symmetry," "zero velocity wall," and "free surface." A plane of symmetry indicates that fluid flow on either side is a mirror image, while a zero velocity wall signifies a stationary boundary where Vnormal equals Vs equals zero. A free surface refers to a fluid interface that is not in contact with a rigid wall, exemplified by the surface of water in a glass. Understanding these terms is essential for effective computational fluid dynamics analysis using Polyflow.

Moving to engineering, but this is pretty specific. It might be best to seek their official support.Baybora said:A computational fluid dynamics program
A free surface is a fluid surface that is not attached to a rigid wall. It's like the upper surface of the water in a glass of water.Baybora said:What is the "plane of symmetry", "zero velocity wall" and "free surface" terms which I have seen in Polyflow? It says in Vnormal=Fs=0 for plane of symmetry and Vnormal= Vs= 0 for zero velocity Wall. Now I get when Vs=Vn=0 it means that the wall isn't moving and it's in a static state but didnt get what others actually mean in linguistics?
Thanks from now
