Dear all,
     I would like to create periodic and flexible( mentioned in paper[1] )boundary condition in DEM-PFV model, but I don't know how to set flexible boundary condition. And I want to know how to set different boundary conditions on different faces. As far as I know, when flow.bndCondValue=[0,0,0,1,0,0] is set, only the upper surface can impose the pressure and the others is impermeable boundary conditions.  Similarly, If use PeriodicFlowEngine to introduce fluid into the system, how to  set different boundary conditions. 
    So, I want to ask two questions.
    1. does flexible boundary condition exist? if does, how to set?
    2. how to set different boundary conditions on different faces, especially periodic and flexible boundary.
    
    Thank you for any suggestions.
