nonuniform inlet velocity boundary condition

shouvik ghorui · June 2, 2020, 17:54

hello everyone, I try to simulate cd nozzle for that I have given pressure inlet as totalpressure and at the pressure outlet fixedValue .and velocity for inlet and outlet are kept as zeroGradient now I try to give nonuniform velocity condition (parabolic velocity) can you give some suggestion about this? like which boundary condition I can use? and how I can implement nonuniform velocity?
and can I give nonuniform velocity in the type pressureDirectedInletVelocity?if yes how i can implement?
thanks
it will be great if I get the help.
