January 18, 2017, 22:18	Velocity appear at zero timestep.	#1
wingkin New Member Join Date: Jan 2017 Posts: 1 Rep Power: 0	Hello, everyone. I am a beginner of FLUENT and now simulating a impinging jet with axisymmetric method. I set a velocity inlet boundary conditions at the bottom of a cylinder. At zero timestep of the result, velocity appear a little at inlet boundary. Why the velocity can appear at very beginning? Could someone explain it？ Thank you!
