Re: help me !

Dear mathias,
Thanks very much for your message, you mentioned that I just need to change the boundary condition, but I’m still confusing about this, as far as I know, to model the moving boundaries, the Bouzidi boundaries should be modified, and an expression term should be added. Am I right? Should I modefied this in OpenLB?Or there is anohter simple way. Look forward to your reply! Thanks very much!
