hai all
my geometry is a rectangular having 10mm in x direction and 1mm in y-direction. 
 the first half ( up to x=5mm) consists of one fluid and second half consists of other fluid having same properties.
top and bottom walls are moving walls with 0.05m/s velocity . the left and right boundaries are stationary.
at x=5 mm i have two edges. 
I want to equate the shear stresses on these bounadires. is it possible in COMSOL?
Hi Siva,
Did you solve your problem? I am facing similar problem.

                                                    Hi
are you using TPF (two phase flow ?) in which case the "continuity" should be done by default by COMSOL, however I'm not fully sure how to set the two boundary conditions to get this to look nice, I tried with two inlets of known velocity gradient but then I block the outflow of one species
The model is v4.3a  TPF  Level set laminar and take some time to solve ;)

Good luck
