I have the similar question about this topic. I have used dynamic method to make my object which covered by a smaller domain moves in fluid. The interfaces dont have any connection or changing respectively. I have choose the internal walls (trg )are rigid body and external walls (src) are deforming. In conclusion, I want to have the connection (remeshing etc.) to fulfill the gap, is there any suggestions for my problem. Thanks a lot
