Dear, all
I am just following the model "www.comsol.com/community/exchange/118/"
which is modeling the free surface motion.
That is made in version 3.5 a
I found difficulty in the WEAK TAB
3.5 : Equation system >Physics>Boundary settings>Weak>Pressure>u, v
4.1 : Laminar flow>weak contribution(?)
There are no "u, v" tab in 4.1 weak contribution .
How can i apply 3.5 boundary condition to the same in 4.1 ?
Any comments will be appreciated.

Hi
in V4 you type in your equations, with the variables you need, to see them and to cmpare to 3.5 the easiest is to turn on the equation view (sub-nodes) and compare from there
The GUIs are different, but the underlying eqautions are the same to the variable naming convention that differ a bit ;)

Good luck
