Dear Foamers,

some time ago I posted a problem with interFoam simulating stratified, smooth flow of water and air. The velocity profile is quite different form the analytical solution.
After a long discussion with the advanced users of OpenFoam at my university in Freiberg / Germany I am not sure anymore, if it is a simulation error of mine or a bug.
Please visite the following thread
interFoam - stratified flow - problem with shear stress at interface
. As I need this simulation for my diploma thesis, I would appreciate your help very much.

Thanks, Anja

P.S.: I made a new test for the transformer oil. I changed the location of the interface in a way, that the average velocities in both phases are the same. Thus, the interface is located at the maximum of the velocity curve and the shear tress is at a minimum.
The same test with air - water combination did not work out that well.
