Hello All,
Do anyone has an idea how can I define an acceleration for the fluid at inlet? Thanks in advance, Pavelko |

The force to accelerate the flow has to come from somewhere. So model the driving force, not the acceleration. Either use a momentum source or a pressure boundary to accelerate it.
