Dear friends, hi, I have a two phase flow problem including a bubble and I am using moving mesh method. I want to apply periodic BC to the top and bottom of my computational domain. Every thing is Ok till for example when the bubble reaches the bottom of the domain. What expected is that the bubble continues to fall and begins falling again from the top boundary, but this does not happen. When my bubble reaches the bottom boundary, I get an error and Comsol stops computing. First, Is there any way to solve the problem? Second, if periodic boundary condition does not work with moving mesh method, why is it includend in the boundary conditions?!!!
Thank you very much Hamid
