Hi friends,
I am working on bubble rising with COMSOL and its moving mesh method. I use periodic BC for the top and bottom boundaries. When the bubble rises from the bottom boundary and reaches the top one, I get an error and COMSOL stops computing. It seems that it cannot continue the simulation again from the bottom boundary. My question is that: Is there any possibility to use periodic boundary condition with moving mesh method of COMSOL for my problem?
Thank you
Hamid
Hamid Moezzi could you put up picture that shows your problem? Is the periodicity kept as the mesh moves?

The bottom and free surface correspond to different boundary conditions. So periodic (in this direction) approach is not correct.
