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.
