huxiaoxia New Member huxiaoxia Join Date: Oct 2010 Posts: 18 Rep Power: 15	Hi, I want to simulate the thin liquid film flow on the substrate and I need the periodic boundary condition for left, right, front and back sides of the domain. However, only the front and back sides work. When I put the cyclic BC on left and right, it shows the error "Attempt to cast type wall to type lduInterface". Does anyone know what's the problem and how to solve it? Thanks.
