Question about the hydrodynamics

Hello, EE Group. I have a question about the hydrodynamic simulation. When I simulated the velocity of a lake in EE 7.1, the velocity were incomprehensible, it appeared the inflows and outflows in some areas where havenot the boundary conditions, and the direction of velocity was incorrect. The boundary and velocity were showed in the pictures. I do not konw why, so can you explain me the reason? Thanks. Attached files

Can you attach the model here or send to jdevkota@ds-intl.biz so we could look at model and see if the velocity (magnitude and direction) were computed correctly or not ?

Thanks.
